Those two are definitely females. One silver laced Wyandotte, one Easter egger.
The other three are cockerels. Yo have to decide if you want to keep any cockerels, first off. There are benefits and negatives to having a cockerel/rooster. They can protect a flock and they can give you hatching eggs if you want to raise your own chicks. On the negative side, they are noisy, your feed bill will go up and your amount of eggs won't, and some roosters can be aggressive.
You could choose to keep 2 or even 3 of them-- they may get along since they've been raised together, but they may not. And all of those negatives I described are doubled with each boy you add. And 3 roosters for anything less than 25-30 pullets probably wouldn't work.
If it were me, I might keep 1 and only 1. If you decide to keep one, choose one that is even tempered but slightly skittish. You want a rooster that is a little afraid of you to avoid trouble down the road. But don't feel guilty if you want to get rid of all 3. Someone will want them. You can advertise on some of the forums in here, on Craigslist, and probably at your local feed store for people who might want them.
Good luck!
