If the hexagons are regular, it has 3 quartets of parallel lines and one 6-tuple of parallel lines.
If the bases are irregular hexagons, it can have six pairs of parallel lines and one 6-truple.
A hexagonal prism need not have any parallel lines, but it can have 18 lines which are parallel to at least one other line.

For a uniform hexagonal prism, there are four pairs of parallel sides. On a hexagonal prism, the six side faces have interior angles of 120 degrees, so each face is parallel with one three over from it. The ends (base and top) are parallel and 90 degrees from each side.

There are 6 parallelograms in a hexagonal prism.
A hexagonal prism is a prism composed of two hexagonal bases and six rectangular sides.
A hexagonal prism is a polyhedron. Many hexagonal prisms are polyhedra.
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.
