The parallel bases would be the two triangular faces, on either end of the prism.

Both a cylinder and a prism can have parallel and congruent bases.
Its "bases"
A prism
No.But is does have two parallel and identical bases.
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.
Both, a cylinder and a prism have two faces (bases) at either end. These are parallel and identical. A plane that is parallel to these bases will cut the cylinder (or prism) in identical cross sections.
Yes, every prism has 2 parallel bases.
