I guess about 1E+16.

Countless trillions of stars would be blocked. You would be blocking out an entire region of the universe. It may be an insignificant part of the whole, but still an enormous expanse.

You would need to make assumptions about the topology of space time to discuss this one fully. If far enough away, entire galaxies could be blocked by the hair. Ever heard of Olbers paradox? It relates to discussion of this question.

None. The hair would be out of focus, and it is narrower than the lense of your eye---much narrower compared to a telescope lens. To block a star, it would have to be wider than the lens.
