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. It is the opposite sides of a regular octagon that are parallel and congruent.
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.
No, a regular octagon has 8 congruent sides
In a regular octagon, there can be multiple sets of parallel lines. Specifically, each pair of opposite sides of the octagon is parallel to each other. Since an octagon has 8 sides, there are 4 pairs of parallel lines, resulting in a total of 4 distinct sets of parallel lines.
8 if it's a regular octagon

A regular octagon has four pairs of parallel lines.
A regular octagon has four pairs of parallel sides.
Any even-sided, regular shape will have opposite sides parallel. A square, hexagon, octagon and decagon are just four examples !
An octagon can have congruent angles if it is regular, meaning all its sides and angles are equal. In a regular octagon, all eight internal angles are congruent, each measuring 135 degrees. However, an irregular octagon may have varying angles, so the number of congruent angles can differ. In summary, a regular octagon has eight congruent angles, while an irregular one may have fewer or none.
if it has all congruent sides, then it is regular
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
