would these guys also count as Draugr?

I love this monster, but how is it CR 3? Compare it to the Minotaur. Same armor class, but the minotaur has 76 hitpoints compared to the wight's 45. The minotaur also hits twice as hard, despite only having one attack, moves faster and has an attack that can knock prone. Oh, and the minotaur's attack bonus is +6. By challenge rating statistics, a CR 3 should have 101-115 hitpoints and be doing 21-26 dpr. This bad boy is doing maybe 14 dpr (if not using lifedrain) and has less than half that much health. Sure it has damage resistances, but it just feels underwhelming. Plus, the lifedrain doesn't even heal the wight. It just leaves a status affect that isn't necessarily useful in the fight - at the price of doing a lower damage attack.

I guess it's because it can summon max of 12 undead with it. 

Thank you.

Second mommy encounter. She is a mommy that was killed by a former member of the forrest who was exiled upon learning that they killed their wife to pursue their sexuality within the forrest. This, however, did not stop her from seeking vengeance on the forrest that took everything from her. 

Kind of weak for CR 3. Its attacks are weak, and deserve 1d6 necrotic damage or +1 strength.
Its defense is overly reliant on non-magical weapon resistance, and is otherwise weak due to low HP, mid AC.
This monster should be CR 2 or get some buffs, it would struggle in 1v1s with CR 2 and 3 creatures even when their damage would be resisted. 
Aside from "This is CR 2", this is a monster that stomps on commoners and guards (but not veterans or knights) but will die easily to an adventuring party.
This is a monster that sneaks around during an undead attack, killing guards and raising zombies, and MAAYBE ambushing the party when they're in a bad spot.
In most other situations, it's weaker than a zombie ogre, and not built for frontline fighting, or fighting a party of Player-Characters.
 

 

level 4 party of 6 as a side fight, how reasonable is this I'm not really an experienced DM

 Check out https://www.dndbeyond.com/encounter-builder if you haven't, it's pretty helpful for getting a ballpark estimate, but personally I think they should be fine fighting one and maybe even two wights.

I have a very specific question. Do wights bleed?

I might use these to represent the 3.5 Necropolitan for reasons.

Question: The Forgotten Realms Wiki states “The name "wight" is of Germanic origin. It began as a general word meaning "being" or "creature", but over the years it was increasingly applied to spirits of either good or evil until it was connotated with the supernatural”. So since it is Germanic in origin, is it pronounced Vight or White? I say Vight, but wanted clarification/opinions.

 "of Germanic origin" doesn't mean "burrowed from German", it means it comes from the Germanic (you know, the language family) part of English. Specifically Wight comes from Old English Wiht, meaning creature

You really should be careful about following some of these DDB pronunciations. For example, Duergar is a real Swedish word and pronounced Dver-gar - two syllables, but f you listen to the DDB pronunciation is is Du-er-gar - three syllables. I am just sensitive to making some of these words sound like an ignorant Americanization is taking place.

 Yeh, because it isn't burrowed from Swedish. It comes from the Latinised version of the norse myth zombies.

I could see a wight being ordered by the dark power that gave them undeath to collaborate with or serve under a necromancer, especially if that necromancer also serves that power.
