What genders are my 4 cornish cross chicks?

[Kennas_Kritters]

I have 4 cornish cross that are 5 weeks old and would like to figure out the gender of them. Pictures have colors on them to match their band colors so I can identify them. What do y'all think they are? I got 2 pictures of each hopefully that's enough. Please excuse the dirt on them lol.

Blue is a cockerel. The others may be pullets.
