Hey guys, I'd appreciate some expertise. I've got three for you today.
Thank you in advance!
 
The first two are fairly similar to my untrained eye, but with distinctly different coloration. The first one is brown, the second one is significantly darker/black.
 
Queen A
1. Location (on a map) of collection: Zagreb, Croatia
2. Date of collection: early morning 06.07.2021.
3. Habitat of collection: She came into my house
4. Length (from head to gaster): 9 mm
5. Color, hue, pattern and texture: fairly uniform brown 
7. Distinguishing behavior: docile
8. Nest description: not observed
9. Nuptial flight time and date: probably evening 06.07.2021.
 
 
She's a bit camera shy. Pics:



 
 
Queen B
Compared to A, much darker
 
1. Location (on a map) of collection: Zagreb, Croatia
2. Date of collection: 11.7.2021.
3. Habitat of collection: She came into my house
4. Length (from head to gaster): 9 mm
5. Color, hue, pattern and texture: fairly uniform black
7. Distinguishing behavior: quite nervous. She attempted to fly while I was putting her in the test tube.
8. Nest description: not observed
9. Nuptial flight time and date: probably evening 10.7.2021.

Finally Queen C
This one was caught last year. Her friend, a similar looking queen caught in the same location within 2 days was IDed in here. I'd say they are the same species, but I thought better check with you.
 
1. Location (on a map) of collection: Zagreb, Croatia
2. Date of collection: September 24 2020
3. Habitat of collection: city center
4. Length (from head to gaster): 5-6 mm
5. Color, hue, pattern and texture: black, with brown rings on abdomen, yellow legs and antenae. A bit hairy
7. Distinguishing behavior: still hasn't shed her wings after 10 months
8. Nest description: not observed
9. Nuptial flight time and date:

Like I said this one was caught late last year and has already spent one winter in hibernation. She currently has a few workers, they are yellow, about 2 mm long. Due to my stupidity they may be malnourished, so I'd expect the upcoming workers to be somewhat larger.
Pics:
There are a few better pics of the aforementioned friend that I suspect to be the same species in the linked topic, but these photos are of the queen in question.





The ligh green grid in the background is 10 mm.

I believe queen B is Lasius niger or some other Lasius sp

queen A may be a crematogaster of some kind but better wait someone more experienced than me.

Queen A could be Prenolepis, Queen B could be L. niger and Queen C could be Solenopsis fugax.

Queen A: Probably Lasius emarginatus

Queen B: Lasius alienus, or Lasius niger.

Queen C: Solenopsis fugax.
