Ok, based on the first set of pictures, your 3 is a cockerel. I believe 1 is as well with those red wattles. 2 and 4 are harder to see. Your second set of pictures are more confusing to me. I can see the black roo in the bottom 2, but it's the pics on top that are confusing. I can also see a roo in those pictures. Probably the one that was in the first picture in the first set. Individual pics with a #1, #2, #3 and good clear shot of the wattles and comb would help. I'm really leaning toward all cockerels currently, but really hoping 2 are pullets for you.
