New chicken owner! Need help sexing! I

[Hickroyhens]

Hello! I am new to the chicken world, spent a lot of time around chickens when I was younger but never much invested in sexing them.
I got 4 2.5 month old chickens from a friend that ordered hens from meyers (queen greens and Easter eggers) the one acts large and in charge. I didn’t know if she was maybe a he
Also got some chicks and they are from a friend who hatched! (Mixed breeds) They are three weeks old and I think there may be one roo!
Appreciate any help !
1st 5 photos are 2.5 mo old, 2nd 2 photos are chicks. I think the light colored chick with the black spots is a rooster!

Welcome to BYC!

All your 2.5 month olds are pullets!
As for your younger ones I'm thinking you have 2 cockerels and 2 pullets, although they're a bit young to know for sure.
