Five.
The differnence is that a triangular prism has 5 faces and and rectangular prism had 4 faces.
Octagonal prism - Number of vertices-16 Number of rectangular faces-8 Total number of faces-10
A square prism (a cuboid with at least two square faces at its ends).
A prism has two polygonal faces at each end and these may have any number of sides, n. The prism also has n rectangular 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.
There are eight faces on a hexagonal prism.

A prism with 16 vertices must be an octagonal prism and so has 10 faces.
A square prism (a cuboid with at least two square faces at its ends).
A prism has two polygonal faces at each end and these may have any number of sides, n. The prism also has n rectangular faces.
A triangular prism has 5 faces, 9 edges and 6 vertices
Oh, dude, a prism with 20 vertices has 10 faces. Each face of the prism connects two of the vertices, so you gotta divide the total number of vertices by 2 to get the number of faces. Math can be pretty chill when you break it down like that.
