The lateral sides are usually rectangles so each would comprise four right angles. However, the bases can be any pair of congruent triangles.

A triangular prism has 5 faces and 6 vertices. At each vertex it has three plane angles - making 18 two-dimensional angles.
A triangular prism reflects light at specific angles. Many are used in equipment such as binoculars and telescopes to reduce their physical size.
You cannot since the triangular prism has faces meeting at 60 degrees - all the faces of a cube meet at right angles. You can have small cubes sitting within a triangular prism but they cannot "fit" into it.
A triangular prism can have right angles. If the prism has two triangular ends, then each of the three 'sides' meets each of the ends at right angles.

It has 12 right angles. 4 on each rectangular side. 3*4 = 12

A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.
