p = a. In a regular polygon with an even number of sides, every side is parallel to the one opposite it. So all a sides are parallel.
Infinitely many.
It is possible, but not necessary. A hexagon can have 0, 2, 3, 4, 5, or 6 parallel sides. A regular hexagon has 3 parallel sides.
Not as a regular 5 sided pentagon but quite possible as an irregular pentagon.
No, none of the sides are parallel on a regular pentagon.

Providing that it is a regular 6 sided hexagon then it will have 3 pairs of opposite parallel sides. Though an irregular hexagon (shaped as the outline of an L) can have 2 sets of three parallel sides.
This is possible, but not necessary. A regular hexagon has 3 pairs of parallel lines, making 6 parallel sides altogether.
This is possible, but not necessary. A regular hexagon has 3 pairs of parallel lines, making 6 parallel sides altogether.
It is possible, but not necessary. A hexagon can have 0, 2, 3, 4, 5, or 6 parallel sides. A regular hexagon has 3 parallel sides.
It is possible but not necessary for a hexagon to have 3 pairs of parallel sides. In particular, a regular hexagon has 3 pairs of parallel sides.
None normally in a regular 5 sided pentagon but it is possible to construct an irregular pentagon with a pair of parallel sides.
Not as a regular 5 sided pentagon but quite possible as an irregular pentagon.
No, none of the sides are parallel on a regular pentagon.
No lines are parallel in a regular pentagon.
A regular octagon has four pairs of parallel sides.
