Prisms with any number of sides can have perpendicular faces. Often both end faces are perpendicular to the length. In the case of a REGULAR octagonal prism, there will be four pairs of parallel faces, where each face of a pair will be perpendicular to the two faces of one of the other pairs. There is not much that can be said with certainty about an irregular octagonal prism.

A pentagonal prism has only 7 faces. Each of the five lateral faces is perpendicular to the two bases: that makes 10 pairs of mutually perpendicular faces. In general, the lateral faces are not perpendicular, but four of them may be perpendicular to one or more of its neighbors - at most 4 more pairs. Still not 25!

There is no such shape as a perpendicular prism.

A rectangular prism has 3 pairs of congruent faces

A rectangular prism has six faces, and each of them is perpendicular to four others.

All of the adjacent faces are perpendicular. So there are 6 faces x 4 faces adjacent to each face So there are 24 perpendicular faces in a rectangular prism.
