ID help on my first chicks please

[ChickyFam3]

Hello! Newbie member and new chick mama here. We got these 5 beauties about a week ago from a friend with a large flock. They are "barnyard mixes" and I'm not sure even about age. If any of you experienced folks have an opinion on age, gender (too early to tell I'm sure), and especially possible breed mixes, I would love to find out more about my new babies! A few specifics about a couple of them.
#2: this is the biggest of the group but may very well be a different age. This one is also growing little white feathers on its legs/feet.
#4: smaller than the rest, seems to be younger. Very sweet.
#5: bravest and most curious of the group. First to check out anything new. Number 2 and 5 seem to get in staredowns and fly up at each other on occasion.
Thanks for any opinions!

Hmm... Mabey 1 week old because of the feather growth on the wings, but I'm not sure.

1 looks like an Easter Egger and 5 looks like maybe a sapphire gem or a sapphire olive egger. 3 looks like a golden or red sex link. Maybe a light brahma for 2 and 4 might be a meat bird but I don't know for sure.

And I would say 1-2 weeks for the age. Where did you get them?

We got from a family friend with a large mixed flock. But I know she has EEs, Brahmas, various Orpingtons, Barred Rock, etc. That's all I can remember right now.
