Help! Boys or girls? Different breeds

Hi everyone! I'm brand new to this community and to backyard chickens in general. I got some chicks from a place where they are sexed but now it seems like they are roosters. I only have 5 and I am afraid 3 might be roosters. What do you think?

Black Australorp






Uncertain age: 5-6 weeks?
He/she has always been really curious and holds herself really tall. Always trying to look out the window and she is always the first to run up when I come to their cage. She's the second most dominant in the group. Very smart.

Easter Egger




Uncertain age: 6-7 weeks?
He/she is definitely the most dominant. It's neck feathers puff out when it's being aggressive and it's always stating it's place in the pecking order. It's tail feathers are a bit pointy. A couple of times it made this screaming sound. Also very smart and not shy.

Easter Egger/Phoenix cross






4 Weeks
He/she is also pretty curious. About in the middle of the pecking order. Doesn't really do anything else roostery besides seem curious and always comes when I have food.

Thanks for the help

All look like cockerels.

Shoot, how bad luck is that. Are you sure?

The only one I'm not 100% sure of is the Australorp, but that comb is a bit too pink for a pullet. The Easter Eggers are no question cockerels.

All cockerels

agree with junebuggena. The Australorp is looking like a pullet but not positive. How old are they?

All roosters, especially that Australorp.

The two Easter eggers are positively male.

The Aussie, I'm about 60% sure it's male, just not positive. Post that one again in 3ish weeks.

The EE's are definitely cockerels, from their pink combs and the red splotches on their wings.
Australorp I think is a cockerel as well.

They definitely all look like handsome little cockerels to me.
