There is no such shape. There is a heptagon (7-sides) or an octagon (8 sides) but not hectogen!

The slope of both lines is 8. So they're parallel.
It depends on the exact shape. Not 8, but there can certainly be 1.

An octagon had four pairs of parallel lines.
None.
An octagon need not have any parallel sides. But it can have any number from 2 to 8 lines that are parallel - in pairs, triplets or quartets.
If lines m and n are parallel, and 8 measures 110o, which is the measure of 7?
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Some of these have no parallel sides whereas a right hexagonal prism has 3 quartet of parallel sides and one sextet.
Yes. Parallel Lines are also two coplanar lines that do not intersect.

The figure that has 4 pairs of parallel lines and 8 obtuse angles is a rectangular shape known as a rhombus. A rhombus is a quadrilateral with all sides of equal length and opposite angles of equal measure. In a rhombus, each pair of opposite sides are parallel to each other, resulting in 4 pairs of parallel lines. Additionally, since a rhombus has 4 angles greater than 90 degrees, it will have a total of 8 obtuse angles.
