Most people would consider the 2 triangular end faces as the bases and the 5 rectangular ones as lateral faces.
I think it has 2 base the answer is 5
A triangular prism has 5 faces, 9 edges and 6 vertices
A triangular based prism has 6 vertices and 9 edges.

A triangular prism has 6 edges and so an octagonal prism will have 16 edges.
A triangular-based prism has five flat faces: two triangular faces at the top and bottom, and three rectangular faces connecting the corresponding sides of the triangles. The triangular faces are parallel to each other, while the rectangular faces form the sides of the prism.

five A triangular based prism has 5 A triangular based pyramid has 4 and there is no such thing as a triangular based prism pyramid - unless you mean a truncated pyramid (or a frustum) which is essentially a prism.
A triangular based prism has 6 vertices and 9 edges.

4...... thousand bases

four!
Assuming that pirsim is meant to be prism, the answer is that a triangular based prism has triangular bases!
a triangular prism, square based pyramid, rectangular prism and much more
A triangular prism has 6 edges and so an octagonal prism will have 16 edges.
It could be called a pentahedral prism.
A triangular prism has a triangular base. A square-based prism has a square base. A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
You can call it a "triangular prism" rather than "triangular based prism" ... saying a prism is "triangular" imply that the base is a triangle. There's no other name that I know of. A prism is just a 3d shape, so all you have to say is <type of shape> + prism to get the point across.
