The only way to make a rooster is to wait for the chicken and cock to mate. You have to hope for a boy because you've got 50/50 chance of getting a boy or a girl.
Not usually, but they can make sounds very similar sometimes. When there is no rooster with a flock it is possible for the dominant hen to make a call somewhat like a rooster. It is always less forceful, more hesitant and of less duration than an actual rooster.

If you are taking about the hen sitting on eggs then it will make things easy for you and the hen. you will have a better outcome if you move the hen or take the rooster out.
The possessive form for the noun rooster is rooster's.
You do not need a rooster for a hen to lay eggs. A well feed, happy hen of appropriate age will lay about one egg a day. If a rooster is around the eggs will be fertilized and you get more chickens, if not you get yummy eggs to eat.
Not typically. Any breed of hen can make a crowing sound but it is often done by hens in a flock that has no rooster. The alpha hen in a flock of chickens without a rooster will often take over the "guard" duties of a rooster.
