Anakis sees the toad is held up in a net in the tree, but the lizard is bearing down on the party. "Better deal with this thing before it starts hurting my new friends." She says as she draws up power into her palm to create a fire bolt and throws it at the lizard (Attack: 12 Damage: 7; and if I have advantage: 22). Anakis then turns and runs towards the toad to keep distance from that giant lizard!

The fire penetrates the lizard's thick scales, harming the creature, but fails to dissuade it from hunting down its prey.

Seeing that the lizard has lost some ground due to getting caught in the net, Fluin bears to the right, getting out of the way of the marsh ponies and hoping to catch the lizard a bit farther along its path. Pausing for a moment, he lets his handaxe drop again, and drawing a javelin, he lets it fly at the lizard. Attack: 7 Damage: 6

As he gets clear of the herd of marsh ponies, it becomes apparent that it wasn't only Fluin that had spooked them. Something is moving through the woods behind him from near the edge of the frozen pool and is in pursuit.

The toad strains against the net to try to break the cords and free itself. Strength: 10

The toad breaks through the net and hops away a short distance before slipping and falling prone in the mud. It lands near the edge of a deep cut made by peat gatherers and barely saves itself from falling in.

Fluin curses under his breath as yet another javelin misses. "Uh, guys?" he call out to the party. "I think we got some company over here in the woods!"

Torrent, the cloud of blood-sucking midges that swarm over you are repelled as the light of Pelor fills you with energy to go on. You're lying prone at the base of the bare ash tree. The approaching lizard is over 135 feet away from you, and the fleeing toad is over 50 feet away from you. What do you do?

Torrent gets up to his feet, trying to catch his breath.  He is tremendously thankful for the hunters' nets.  He looks over his shoulder at the approaching lizard and calls out, "Imma need *puff* some help *wheeze* with biggin' here."  He then starts to limp away from the lizard in the direction of the toad.  "Yer... much... more trouble... then yer worth."

Tarek, the giant lizard, having momentarily lost sight of Torrent while he was down, fixes its gaze upon you instead and continues its approach directly towards you from across the frozen, marshy field. The toad, having again fallen prone, is a little over 45 feet away. What do you do?

Aluzira, you're aware that the lizard was momentarily slowed down by the net (although it continues to charge) and that Fluin has noticed something following him in the woods behind. What do you do?

Aluzira runs towards the lizard, not wanting to lose to much ground on it.  Then, hoping to catch sight of what's chasing the ponies as it breaks through the woods, she looks around to where the ponies are running from.  "Please be good company," she says hopefully.

As Tarek notices the lizard fixing its gaze on him, Tarek begins to fix its gaze on it. "On it!" he says in response to Torrent. He will just use his normal movement to approach the lizard, rapier in hand.

Aluzira, you can aim for where the lizard will likely be on your next turn (about 60 feet away), but you'd have to dash on your next turn to get there. Or you can aim for where the lizard will probably be on your following turn (about 50 feet away), and you'd be able to use your action for something else on your next turn (and the following one when the lizard will hopefully be within your reach). Do you have a preference? 

Edit: You can also move directly toward where it is now with pretty much the same result as the first option above, but in either case, you won't reach the lizard until after dashing on your next turn. 

(Aluzira will go with the second option.)

Aluzira, you come out of the wood into the open, but the lizard remains transfixed by the challenge of Tarek's gaze and continues charging towards him, dragging behind it ragged bits of the net.

The marsh ponies  are rounding the edge of the frozen pool, doing their best to stay out of the icy water as they push their way through the dense wood behind you. Whatever spooked them is too far back among the trees to be seen by you at this time.

Ulben, you also can hear whatever it is that spooked the ponies and now seems to be chasing Fluin who's a few feet to your left. It's about 45 feet behind you in the woods, coming in your general direction. You're still 40 feet from the treeline, the rest of the party at least another 55 feet beyond that. What do you do?

Do you continue to try to reach the rest of the party, Ulben?

Yes

OK, Ulben, you're nearly out of the woods. You hear the unknown creature continue to dash forward behind you.

Suddenly, everyone except Torrent hears a woman's voice cry out loudly from the unseen figure in the woods, "Stand ho, city dwellers!" The voice speaks with a thick accent, and some of its words are strange to you but are mostly understandable. "Have thee not seen the markings? This ground belongs to the Bright Spirit Kin. Trespassers may not hunt hither!"

Anakis, the charging lizard is now about 90 feet from you, and the toad is 100 feet from you and is once again lying prone. Torrent and Tarek are between you and the toad. The unseen voice in the woods comes from about 110 feet away. What do you do? 

Ulben is yelling "Ohhh $#!+ Ohhh $#!+ Ohhh $#!+" Over and over while running.

"Tell that to the big lizard lady! We're not hunting, we're being hunted!" Anakis yells as she lets loose a fire bolt (Attack: 14 Damage: 2) at the lizard and continues to run towards the prone toad for her full movement.

"Who're ye yellin' at, girl?"  Torrent yells as he runs.

The fire leaves scorch marks on the lizard's scales as it quails in fear of being burned again. 

Fluin, seeing the lizard pause in its charge, and determined to defend his companions at any cost, ignores the voice's warning and charges straight for the lizard, breaking through the trees and out into the open. "I'm going to protect my friends," he shouts at the unseen woman behind him, "and you can't stop me!"

The toad, once again scrambling to its large, webbed feet, hops forward and lands with a splat in the mud, breathing rapidly with exhaustion and panic.

Torrent, the toad is now 75 feet ahead of you, lying prone in the mud. What do you do?

Edit: Sorry, I said on your last turn the toad was 50 feet away, but it should have been more like 80 feet.

Torrent, blind with rage and exhaustion, sprints forward trying to catch up to the toad.  "I'm... gonna... get yeh... yeh d***ed thing."

Tarek and Aluzira, after being hit with Anakis' fire, the lizard has stopped its charge. It's over 100 feet from Tarek and 35 feet from Aluzira. What do you do?

"Guys, I think we should stand down," Aluzira calls out to the group.  Then to fill torrent in says, "There is a lady here who says this is Bright Spirit Kins ground, and trespassers may not hunt here.  I think Bright Spirit is Pelor, and that would mean this is his ground."  Although Aluzira doesn't follow a specific Deity, she does her best to respect them.  She slowly moves another fifteen feet towards the lizard, resheathing her daggers before pulling out a bit of food from her pack.  "Lizard, you'd be better off not chasing us, I think,"  she says to the lizard setting the food down next to it, hoping she's as good at calming down lizards as she was with the bears.
