Your armpit is a warm, moist environment where bacteria that release odors can grow if your personal hygiene is not good enough, or if you have a condition that causes more sweating that is common.
It's a secondary sexual characteristic, and a vestige of a time before clothes. That skin is very tender, as it gets less exposure to light and air. It is not desirable nowadays, but in pre-historic times, people could identify others by scent, and pheromones played a big part in sexual attraction for prospective mates.
Because there is no reason not to have hair there.
If you believe in evolution, you have the hair there because there is no reason not to have it there. (hairy arm pits are not a negative survival trait.)
If you do no believe in evolution, it's because God put the hair there.
In either case, the real reply is "Because you do."
It could be the deodorant, lack of deodorant, the growing follicles, or the stubble. If it's the deodorant, you may want to switch brands, or, if lack of use, start using some. Otherwise the latter two are natural, and just need too go through their courses.
to absorb sweating and body smell to keep you warm

The armpit is a heat sink. The hair is to help with the control of heat, specifically to hold moisture (sweat) in the area until it can evaporate, and take the heat with it.
Those bumps are hair follicles that help to promote cooling via sweating.

Gnats come out at night since they are afraid of the light and have itchy bites. When you are bitten by a gnat, you should apply anti-itch cream.
that would come under Aphenphosmphobia - the fear of being touched
it means you have dandruff
Your skin might be irritated. For example, your armpits from razor burn, or your breasts from a bad under wire bra. If you don't think that's the reason check with a doctor or online, or try treating it with some calming cream before seeking medical attention.
