A polygon is a 2-D figure with no faces, so a hozec-agon (whatever one of those is) has no faces.
A 3-D figure (possibly with faces) is a polyhedron.
A cuboid has 3 pairs of parallel faces.
A rectangular prism has six faces, and each pair of opposite faces is parallel to each other. Therefore, a rectangular prism has three pairs of parallel faces.
An octagonal prism has a total of 5 pairs of parallel faces. It has two parallel octagonal bases and eight rectangular lateral faces, with each rectangle having a parallel counterpart on the opposite side of the prism. Thus, the pairs of parallel faces consist of 1 pair for the octagonal bases and 4 pairs for the rectangular faces.
It can have one, two or three pairs of parallel faces.

A cuboid has 3 pairs of parallel faces.
There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.
A rectangular prism has six faces, and each pair of opposite faces is parallel to each other. Therefore, a rectangular prism has three pairs of parallel faces.
An octagonal prism has a total of 5 pairs of parallel faces. It has two parallel octagonal bases and eight rectangular lateral faces, with each rectangle having a parallel counterpart on the opposite side of the prism. Thus, the pairs of parallel faces consist of 1 pair for the octagonal bases and 4 pairs for the rectangular faces.
It can have one, two or three pairs of parallel faces.

A triangular based pyramid has zero pairs of parallel faces. In a triangular based pyramid, all three faces of the base are not parallel to the apex, which means there are no pairs of parallel faces in this type of shape.
A rectangular prism has three pairs of parallel faces. Each pair consists of two opposite faces that are identical in shape and size: two pairs of rectangular faces on the top and bottom, two pairs on the front and back, and two pairs on the left and right sides. Thus, there are a total of three pairs of parallel faces.
