The feathers on top of a peacock's head are called a "head crest"
A rooster with feathers that stick up on its head is likely a Polish breed, which is known for its distinctive crest of feathers. Polish roosters have a unique appearance with a tuft of feathers that stand straight up on top of their head, giving them a decorative and fancy look.

If there are two or more in the same cage, one of the other birds is pulling them out.
They don't, they have feathers on top of their skin.
An impossible question to answer. What species? Different species spend from several days to several months as nestlings and feather growth is similarly variable in timing. What is meant by "grow"? Feathers visible in the skin or fully expanded, orthadox, feathers?
Through it's nostrils and lungs just like a human. The nostrils are located at the top of the beak where the beak joins the feathers of the head
During an aggressive attack, most chickens will grab the comb or head feathers of the other chicken to pin it down on the ground. Constant bullying will result in loss of feathers around the top head/comb area. These are often short but often attacks and may go unnoticed Also mites/lice can cause scratching which results in loss of feathers. Wire runs can also cause this as the chicken rubs its head against the wire mesh, especially if its pecking on something the opposite side.
