Not in the same eye. They are complementary - the eye focuses the distant and the near on the back surface of the eye by changing the shape of the lens. If the eye is too long or too short, the lens can't change enough to bring one set into focus. And with aging, the lens becomes less flexible.

Yes, most definitely, in fact, it's hard to avoid for many older people. If you were mildly myopic (nearsighted, distant objects blurry), by the time you hit about 50, you only have about 1 diopter of accomodation (range of focus) even though you probably had about 25 when you were 15. A mildly myopic person in their 50s will need a concave lens to focus at infinity, and a convex lens to read.
I'm in that boat. In fact, I have several pairs of reading glasses, weak ones for computer work, and strong ones for close work ( I do electronics).
But yes, to many people, their only uncorrected "20/20" vision lies in ranges like from 5 to 10 feet.

Yes ONLY if you are an Emmetropia (Normal distance vision) OTHERWISE IT IS NOT POSSIBLE :)
Everybody wants to be normal, and if your eyes are normal then you are said to be emmetropic. Emmetropes (folks with normal eyes) naturally see clearly in the distance. Anatomically, images in the distance are focused perfectly on the retina by the cornea and lens. AND if you weren't jealous already, these luck devils can also see clearly at near UNTIL they reach the age of about 42.

It is possible, my sister was born with strabismus (more commonly known as having a lazy eye), after surgery she ended up being near-sighted in one eye and far-sighted in the other.

Yes, you can
