The AntsCanada Ant Forum's

I think the first one is Dorymyrmex bureni and the second one is Dormyrmex insanus. The major looks like Pogonomyrmex badius to me

Pics are too blurry. My best guess is Dormyrmex insanus but I can't tell

I agree with melanocephalum No idea about the others but I can say that the third one is almost definitely semi-claustral

Brachymyrmex sp. I would say obsurcior or pantagonicus

You did keep workers, right?

They fly in low seventies and usually near or in hardwood forests. Look at the trees during these days and you might notice some male swarms. Queens are a lot harder to find

They will probably be ok but idahoantgirl, Ants CAN drown

I believe both are queens. Polyrachis is a possibility. Remember, these are semi-claustral

The queen probably had one of those mysterious deaths and was in the process of being thrown out or fed to the brood

Kinda looks like diacamma
