Actually, there is no single answer because a prism is a generic term which is used to describe a polyhedron with two congruent and parallel bases and a number of rectangular faces joining them.

If the base is a polygon with n sides (n ≥ 3), then the corresponding prism has n+2 faces. So a prism can have 5 or more faces.
