squares
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.
Not necessarily.

A rectangular prism has 12 edges with rectangles and squares for faces
There are 7 or 9, depending on the bases.

Not necessarily.
Yes because has parallel edges and faces
Rectangular Prism
Yes, on the edges
It has 5 faces, 6 edges, 4 vertices, and 2 base. Bases are counted as faces too, but are polygonal and are translations of each other in space. So, they are congruent and are in parallel planes. * * * * * The above answer is utter nonsense. A triangular prism has 5 faces (two triangles and 3 rectangles), 9 edges and 6 vertices. Bases are counted as faces.
Usually, a pair of parallel bases and four pairs of parallel lateral faces.
