No, only 1 parallel line
A heptagon is neither parallel nor perpendicular, as these terms typically describe relationships between lines or planes. A heptagon is a seven-sided polygon, and its sides can form various angles with each other. The angles and sides of a heptagon do not imply parallelism or perpendicularity in the same way that lines do.
No, a heptagon cannot be parallel but two heptagons can.A heptagon can be concave.
A heptagon contains zero parallel lines. All of the lines in a regular heptagon with all sides and angles equal are at different angles from each other.

There is no such shape. There is a heptagon (7-sides) or an octagon (8 sides) but not hectogen!
A regular heptagon has no parallel sides.
Not normally unless it's an irregular heptagon which can be constructed to have parallel sides
No
You can have 0, 1, 2, or 3 pairs of parallel sides in a heptagon.
