Looks like a Formica rufibarbis to me given the size of the 2 nanitics, but I added some stolen brood from a formcia sanguinea or rufa colony to be sure, what do you think?

I don't know why but the 2 of my posts merged together, these are obviously 2 different queens

Formica are often difficult to ID without a clear view of the hairs on their body. Does the second queen have any smaller cocoons with her? I fear those pupae are all reproductive caste.

I found the queen alone, they are all the same size except one much bigger and darker one on her left, I though it might be a major, but I guess it's an alate as you said. The other ones are smaller, you cannot see it so clear on that picture
