Pullet or cock? 2 unsure birds

[PenguPen]

OK so I got these chickens from a friend, she said "My hens are all purebred ranging from speckled Sussex,brown leg horn,Americana, and Golden sexlink. Dad is Americana."

They are 8 weeks old today. I got 7 from her 5 I'm sure are cocks.
These two, they don't have the big dark comb like the rest, nor do they seem to be growing waddles like the others. Only way I could get half decent pictures was during feeding time.

Unknown #1 in following pictures. Sorry I don't know how to attach them in the post directly. Other chick will be in the next reply.

3and 4 I'm only show casing 2 birds... I know the rest are cocks... She gave them all to me as cocks... But these two I'm second guessing her judgment.
The one with the golden head, and the dark one with brown across the shoulders

the one with the arrow pointing to HER I believe is a pullet.
