Gender of chicken please?

100% cockerel, it's indisputable. Others have beautifully covered the reasons as to why we answered such.

[Crazy for Chickens!]

At 6-8 weeks, to about 16 weeks, any bird that has a red comb or wattles, is a cockerel. At around 12 weeks, Males will develop pointy saddle feathers. Females will stay rounded. At 16+ weeks, hens will develop red combs and wattles as they get ready to lay.

I'm assuming your chicks are under 16 weeks. I see several cockerels.

You may want to post individual pics of each one's combs, to tell for sure. Also, the age would help.
