I agree with you that you have one obvious pullet (the striped on in the far right of the last photo), two obvious roosters (the two in the middle of the last photo), and two kind of "in-betweeners", which are probably cockerels (the ones on the far left in the last photo). I guess the 50% cockerel/pullet rule doesn't always apply...
