All patched up, Mal'thrae climbs up the side of the tavern onto the roof, hides, and looks for the attackers.

Outside, you see a whole bunch of Gorilla-like creatures barreling into the town. The creatures look a lot like gorillas but they have a more human form to them, their eyes a piercing green and bodies covered in black hair. 4 of them are coming in towards you. (Everyone roll initiative)

Valorie: 16
Spawn 1: 11
Spawn 2: 12
Spawn 3: 22
Spawn 4: 9

Initiative: 13

Mal'thrae Initiative: 12

Gorokum Initiative: 17 

Jadyn Initiative: 5

Basina initiative 13

Here's the initiative:

Spawn 2

Spawn 3

Gorokum

Spawn 1

Thoradin

Basina

Mal

Valorie

Spawn 4

Jaydn

Spawn 2 moves into the plaza, then it gives a strong punch to Gorokum

Attack: 9 Damage: 6

Spawn 3 moves around, trying to reach Mal, but ran out of movement.

Gorokum doges to the side as the Gorilla like creature takes a swing at him. He then centers himself, focuses on the ruins of his staff, and says "Variae armis," and a slight shimmer of energy covers his body.

(Action: Cast Mage Armor And if Spawn 3 is moving around Gorokum, if he's within 5' will use Reaction to opportunity attack: Attack: 10 Damage: 8 )

It passes you, but you missed by about one inch

Spawn 1 does the same as Spawn 2, but attacks Jaydn instead

Attack: 15 Damage: 7

Crit. Damage: 8

(What is their position? Can I get 2 or 3 of them with a lightning bolt?)

None of the spawns are within 15ft. of each other

And none are in a straight line?

No

(bless on Mal, Basina and Gorokum)

Raising his shield bearing the holy symbol, Thoradin invoked the power of tempest to bless several of his teammates.

Basina sighs heavily at the loss of the chance of getting a meal.

Then she will move towards the nearest spawn (spawn 2?) and attack them twice. 
Attack 1: 26 Damage: 11
Attack 2: 20 Damage: 7

If one of them hits she will use divine smite for an additional 8 damage

Critical damage 7

Mal climbs up a low building, then hides.

Stealth: 26+4

He then fires upon spawn 4.

Attack: 23 Damage: 18 magic piercing

Ambush master: auto advantage on spawn 4

EDIT: With the auto advantage, Mal will hide after his shot instead of before.

 Your attack deals heavy damage to Spawn 2, instantly killing it!

 (You have serious stealth-luck)   
Your attack hits the target from afar

Valorie points a finger towards Spawn 4, a fireball forms before flying towards the spawn

Dex: 11 or 20 damage.

Spawn 4 believes it was Valorie attacking it both times, in return, he gives two punches to the drow

Attack: 23 Damage: 8   
Attack: 7 Damage: 7
