It could be a prism, but need not be. A regular dodecahedron, for example, is not a prism but has parallel and congruent pentagonal bases. You can also have any antiprism (see link).

Pentagonal Prism = 2 pentagonal bases + 5 lateral faces Pentagonal Prism = 7 faces Pentagonal Prism has 10 vertices Pentagonal Prism has 15 edges

A rectangular prism has 6 faces. A pentagon prism has 7 faces. Therefore a rectangular prism has one less face than a pentagonal prism.

A pentagonal is not a shape. You an have a pentagonal pyramid, a pentagonal prism or a pentagonal polyhedron as well as other shapes - each would give a different set of answers.

Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.

It need not have any. It can have two.
