Could be a pullet, but hard to say at such a young age; it could go either way. In the second pic, it looks like it has wattles coming in, not a good sign if you're wanting a female. It's hard to tell from the pics, but does it have a single comb?
The highlighted one is a pullet. In the group photo I am sure there are three roosters and one pullet. I cannot see the other one well enough to say since I can only see the crest in the picture; yet the crest indicates a pullet. So I guess it is three males two females.
