Are you wanting assistance on breed or gender..?
I'll gladly make some wild guesses on both
Picture 1) The first chicken- smack in the middle of the first picture- that looks cockerel to me- not knowing any ages

- since that one seems to have more going on than anyone else in the shot- OR- they are a pullet- closer to the POL (slow shrugs) Perhaps this chicken has a bearded booted bantam mix in there..?
There looks to be a silkie pullet in the front, left hand side of this photo.
The black chicken looks pullet from what I can see- not the face- can't see any 'cockerel' feather tells - not here at least

. Not a Cochin. Not a dutch. Wrong shape for a OE, Japanese, or serema. (Slow shrugs) Not a booted or silkie variety...
The others are in motion... but the coloring and shape makes me think they are kin to the center feature chicken.
Picture 2) This looks like a pullet. Maybe an EO mixed with a golden sea bright?
