Spheres
They are faces such that the perpendicular distance between them is the same wherever on either face you measure it.
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.
A cube has six faces, which are arranged in three sets of two parallel faces.
A cuboid has 3 pairs of parallel faces.
There are infinitely many shapes that do.
A rectangular prism has 6 faces because it has 3 pairs of parallel and equal-sized rectangular shapes.

there are three parallel faces in a cube
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
A cylinder has two parallel congruent faces and a curved surface.
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
Bases are faces but faces are not necessarily bases.
