I see a bunch of Lasius queens in your pictures (although nobody should have been able to identify the workers to the species). I can't see them clearly at all, but at least one of them looks like a Lasius umbratus queen. I wouldn't be sure that any of these are their workers, though, unless they are being friendly with each other.
If you've enjoyed using my expertise and identifications, please do not create undue ecological risk by releasing your ants. The environment which we keep our pet insects is alien and oftentimes unsanitary, so ensure that wild populations stay safe by giving your ants the best care you can manage for the rest of their lives, as we must do with any other pet.
Exotic ants are for those who think that vibrant diversity is something you need to pay money to see. It is illegal to transport live ants across state lines.
