I would agree, after seeing the updated pics, all others look like Cockerels to me, was holding off on #6, but seeing the pattern up close, I'll say Cockerel for sure now.
I agree, other than #6 gives me pause, I'm uncertain about him/her, comb is red but at that age, I've had Pullets lay at 15.5 weeks and the coloring is spectacular, maybe I'm just hoping for you that you have a minimum of 2 pullets :confused:
