Genders/breeds for the last two unidentified chicks?

I'm pretty sure the chick in the first picture is a sort maran cross and a cockerel. The second chick I'm leaning towards black australorp/cross and I'm hoping pullet? Her behavior mirrors my olive egger pullet and differs drastically from the suspected cockerel and our known cockerel.

Also, sorry for asking so many questions, I'm trying my best to learn how to identify and sex them.

Age? First one is a cockerel and the second one looks like a pullet. Post more pics in a few weeks.
