You are correct.the two black ones from what I can tell are roosters and yellow one a possible hen.
Depends on what you mean by 'tame'.If my aunt or someone else gives me hens that are about ready to lay or laying will they be easy to tame too? And become familiar with me?
Chickens are prey animals, they naturally want to stay away form anything larger than them.
Even when they are used to being handled, most don't care for it much.
You have to spend a lot of time with them to make them 'cuddlers'.
