The AntsCanada Ant Forum's

Brazil has amazing ants and lots of diversity!
I think they fly all year round there but probably mostly in the rainy season.
Good luck!

1. Probably Acromyrmex.
2. Camponotus sp.
3. Maybe Nylanderia.
4. Pogonomyrmex I think.
5. I'm not sure maybe some sort of Dolichoderinae.
6. Pheidole sp. I think.
7. Maybe Solenopsis but can you make more photos?

Maybe Paratrechina longicornis.

Maybe but there are a few similar species.
Can you make a closer picture?

Amazing place and diversity! Lucky you!
One of your best videos!

The queen is probably Solenopsis and the worker Odontoponera sp.

Lasius are pretty hardy ants so they should be OK at temperatures above 0 °C.
At room temperature they are still active but brood stops developing and the ants are waiting for winter.

Do you keep them in a cold place?

These are small larvae and will not continue developing without hibernation.
You can hibernate them now.
Good luck!

Really? I've never seen anything like it. Can you make a photo?
I recommend hibernating them.
