oh I'm not sure there might be a queen. That's just me though.The top two pictures are not ants. The second one looks like a Crane Fly. Im not certain, but the only two outlines I can make out on your bottom two picture (the ones away from the group) are just a minor and major workers. Their might be a queen in there but I cant make out anybody in the mass of ants, with how blurry it is.
