I can't see the rooster in the first photo well enough to say anything about him. He's not an Araucana because he's got a tail. Araucanas are rumpless, which means no big tail feathers. I don't think he's an Ameraucana either, the comb looks wrong...but he could be an Easter Egger, which is a crossbred bird with Ameraucana or Araucana in its background. He is bearded, so it's quite likely.
Your golden colored birds like the rooster in the last photo are Buff Orpingtons. I see some Rhode Island Reds in the flock picture. (Reddish brown feathers, black tail) Obviously you've got an Easter Egger hen, because of that green egg. The black hens could be Plymouth Rock or Australorp.
