whats my gender:,(
I know it's very hard not knowing the gender, but you have to understand many users have told you their answers and despite that you have managed to ignore everyone who has tried to calm your desperate needs. The lady you got your chicks from was WRONG and two of your chicks might end up being roosters. As I said before, your barred rocks are roosters and the sex link chick is a male as well.
I think what you should be worried about for now while they age a little more is finding them better living arrangements. They need proper bedding, aka, pine shavings from a local tractor supply or something like that, and a bigger pen.
