A dodecahedron has 0 parallel faces
its has parallel faces and edges
A cube has six faces, which are arranged in three sets of two parallel faces.
No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.
A cylinder has 2 flat, parallel faces.
A cube has three pairs of parallel faces and all faces are congruent.

There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.
A pyramid never has parallel faces. Any two faces intersect.
A cube has six faces, which are arranged in three sets of two parallel faces.
No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.
Usually, a pair of parallel bases and four pairs of parallel lateral faces.
A cylinder has 2 flat, parallel faces.
The only two parallel faces on a prism are the ends.
3 pairs of parallel faces
A cuboid has 3 pairs of parallel faces.
