The one closest to the camera in that picture is a brown leghorn. That's exactly what they look like. The lighter yellow ones should be your orpingtons, and the darker, more reddish ones are RIR. The dominiques are black with white spots on their heads, and the ameraucanas (which are actually easter eggers) are what's left. They should have fluffy faces, and can be any color.
My current EE chicks are two yellow ones, who are feathering in white and buff. One light chipmunk one, who is going to be a light reddish brown, with patterned feathers. The last is a very dark one, with a reddish black body and red head. No idea what she'll look like. But they all have fluffy faces.
