Help with breed and/or sex?

[Oranges]

Hello! This is my first post. I would be very grateful for any help identifying breed and/or sex of these chickens. They are 8 weeks old (at least, according to what I was told when I got them.)

Bird 2:

Bird 3:

Bird 4:

Birds 1 and 4:

When they were chicks (1 and 2 were mostly brown, 3 and 4 were mostly yellow):

1 cockerel, the rest are pullets. Not sure the breeds.

I'm not sure on breed, but if the age is right then 2 is definitely a cockerel. The rest are pullets.

Where did you get them?

A friend of a friend. But the breeds I was told they are don't quite seem to match up with how they look, that's why I thought I would try posting.

What were you told they were? I’m thinking that they could be New Hampshire red mixes or even red ranger mixes.

I was told New Hampshire Red, Red Sex Link, Black Sex Link, and Rhode Island Red.
