The polygon may have 2n sides, where n is any whole number greater than 1
An infinite number. Any parallelogram can be cut in half by a line parallel to one of its sides to increase the number by one. And there is no end to that process.

Four: two pairs.
Of a regular hexagon, yes, since it has an even number of sides.
A concave hexagon can have 6 perpendicular sides if you count the external angle of one. The angles would be 90, 90, 90, 90, 90, 270
The polygon may have 2n sides, where n is any whole number greater than 1
a pentagon has 5 sides total, and no parallel sides. A hexagon has 6 sides, so it has 3 parallel sides. any shape with an odd number of equal sides has 0 parallel sides, no matter how many sides it has. every shape with an even number of equal sides will have the # of sides divided by 2 (#/2) of parallel sides.
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.
2 is the answer
Parallelogram Rhombus Hexagon Octagon Pentagon Any shape that has even number of sides.
The largest number possible is infinity
There is no specific name. For example, if you number the sides of a regular hexagon sequentially from 1 to 6, then sides 1 and 3 are not parallel but there is no specific name for that pair. In the context of the hexagon they do not meet - even if they do so way outside the hexagon. If they do meet up in the context of the shape, then they will be adjacent or intersecting sides.
A regular hexagon (if you can use non-regular shapes then there's an infinite number)
