Gender and possibly breed?

[RoostersAreAwesome]

Hi all,

Some of the little guys below, i posted few weeks ago but received some mix responses so I've got some more photos and some new chicks for identification.
Hoping for some assistance in identifying gender mainly and breed if possible?
Ages vary between 6 to 8 weeks.
Last 4 photos are of the same 3 chicks.
Thanks alot!

Do you have updated pictures? Several of them look like sussex mixes. The first one could be a Brahma/sussex mix cockerel.

I'm sorry for the late reply.
Unfortunately, i lost all my chickens in the photos due to sickness, only the Brahma is left and even he is still abit unwell.
I'm trying to help them get better and if they get well, I'll give them away as I'm done with chickens
