No. It is the opposite sides of a regular octagon that are parallel and congruent.
Yes:As the shape is regular all sides are equal in length (and congruent).An octagon has 8 sides. As this is an even number of sides, the opposite sides are parallel.
No, a regular octagon has 8 congruent sides
8 if it's a regular octagon
a hexagon could be adjacent only if it is regular an octagon is adjacent
Any odd sided regular polygon, ie an equilateral triangle, a regular pentagon, a regular heptagon, ...

No, a regular octagon has 8 congruent sides
A regular octagon has four pairs of parallel lines.
8 if it's a regular octagon
A regular octagon has four pairs of parallel sides.
a hexagon could be adjacent only if it is regular an octagon is adjacent
Any odd sided regular polygon, ie an equilateral triangle, a regular pentagon, a regular heptagon, ...
if it has all congruent sides, then it is regular
That could be numerous polygons: a square, a regular hexagon, a regular octagon, a regular dodecagon ... Any regular polygon with an even number of sides could be your answer.
It depends on the actual shape of that octagon. It CAN have two pairs of parallel sides. A regular octagon has 4 pairs of parallel sides.
If you mean parallel sides then a regular 8 sided octagon has 4 pairs of parallel sides
