Am I a cockerel or pullet? Amber links

[Sunshinechickies]

Hi everyone! I have 3 amber links that I bought as all pullets, but I am 100% sure I have a cockerel. What do you guys think about the other 2?

My rooster, and here are the other 2.
Chick number 2, I think she is a pullet but she is a bit larger than chick 3.

And chick 3, which I think is a pullet too. Sorry about how bad these pictures are, if anyone needs better pictures let me know.. I think I have one cockerel and 2 pullets but I would like some second options too. Thanks!

Number 1 definitely looks like a roo, how many weeks are they?

Oh- and they are about a month and a half if that helps, and personality wise- my rooster is super curious and adventurous. Chick #3 is pretty skittish so I don’t get to touch her very often. Chick #2 is pretty calm and laidback, she will let me pet her and likes to lay in my lap.
