The 12 edges of a regular octahedron consist of 6 parallel opposite pairs. In fact, the 12 edges form 3 squares.
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.

There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.

Not necessarily. A heptagon-based pyramid is an octahedron and it has no parallel faces.
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.
An octahedron has 7 perpendicular lines.

its has parallel faces and edges
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The number of parallel edges or faces will depend on the particular octahedron. A heptagon-based pyramid, for example, has no parallel edges nor parallel faces.

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Whether or not anything is parallel depends on which of these octahedra you have in mind and, furthermore, which version.For example, the general hexagonal prismoid will have nothing in parallel. But a special case of the same topological octahedron, a right hexagonal prism, has 4 pairs of parallel faces. It also has three quartets and one sextet of edges that are parallel.
