A pentagonal prism has 7 sides : 5 side faces and 2 bases.However, if all sides of the prism are considered faces, a shape with5 total faces including the 2 bases is a triangular prism.
A general prism has two congruent polygonal bases (faces), while the other faces are parallelogrammatic; a right prism is so-called when the general prism's remaining faces are rectangular.An example of a right prism with two congruent rectangular bases is a cube if all other faces are equal to the bases; a cuboid prism is where the other faces are equal to each other but not necessarily to the bases.
In its most generalised form it comprises two connected, congruent and parallel faces: these faces are called the bases. In a right prism, the bases are at right angles to the length of the prism. In a polyhedral prism, all faces are polygons and, in such a case, the faces joining the bases are quadrilaterals. In the very special case of a right polyhedral prism, the bases are polygons and the lateral faces are rectangles.

They are a pair of congruent and parallel faces of a prism.
A pentagonal prismoid. If the lateral faces were rectangles, it would be a pentagonal prism.

Sometimes,only because,a rectangular prism has two bases and four faces, but a triangular prism has two bases and three faces.
A prism *always* has 2 bases. In case you meant "faces" instead of "bases", the prism with the smallest number of faces is the triangular prism - which has 5 faces. If there were any fewer number of faces, the prism which become a two dimensional object.
A prism whose bases are parallelogram
A general prism has two congruent polygonal bases (faces), while the other faces are parallelogrammatic; a right prism is so-called when the general prism's remaining faces are rectangular.An example of a right prism with two congruent rectangular bases is a cube if all other faces are equal to the bases; a cuboid prism is where the other faces are equal to each other but not necessarily to the bases.

A triangular prism has 5 faces, including one parallel pair; any of the faces might be considered a "base" depending on its orientation.
