Nope, I maintain that the darker one and the bottom bird are both cockerels.
The only female I see is the top one in the second set of photos. She is your Light Brahma also.
I'm sorry, but those birds are not show quality. The first bird in the second set of photos is the only one that may be breeder quality. The first bird is a pullet.
The others #2 and #3 look to be males, and look to be a mix between Light Brahma and dark Brahma.
#4 I am going to say female...
