Help sexing a few 6w old chicks "backyard mix"

[Northernhens]

Hello! This summer I hatched some eggs from a local farm. They were from a fertilized egg pack of "rainbow layer barnyard mix". They are almost 6 weeks old, and in my city Im allowed to keep 6 pullets (I had 20 eggs hatch). My cousin is coming up this weekend to take the 14 extra chickens to her farm for their coop, but I need to figure out which ones I'm keeping for my urban hens.

A number of them were very easy to tell roo vs pullet, but my kids have imprinted on these 4 so I want to get best guesses on if these look female or male to you so I can start setting expectations.

The farm I got the eggs from said that their flock includes the following chicken breeds:

Hens:
Ameraucana (Blue, Splash, Mottled)
Partridge Rock
Black Australorp
Black Orpington
Lohmann Brown
Easter Egger
Gold Laced Wyandotte
Olive Eggers
Barred Rock

Roosters:
Speckled Sussex
Ameraucana
Easter Egger

I would keep an eye on the first one but as of now they all look like they are pullets currently

Yeah, the first one was the one I was most worried about. It seemed more solid than the others when I picked it up, but I didn't know if that was a breed difference or sex difference

#5 looks like a cockerel. The others look like pullets.
