No worries! I do believe the third is a cockerel then. So my opinion is
First: cockerel
second: pullet
third: cockerel
Which would be the same as @OneHappyRooster 😊
Second is a girl. The splotchy coloring on the first one is leaning me towards cockerel, but the comb hasn't gotten red at all. Kinda confused about which is the third one sorry! Can't tell which one you are talking about.
