There are normally three rectangular faces and so their angles are all right angles. But there are no restrictions on the angles of the triangular faces other than that they sum to 180 degrees.
18
It has 12 right angles. 4 on each rectangular side. 3*4 = 12
14 if the triangular cross section has a right triangle, 12 otherwise.
There are twp perpendicular edges in a triangular prism. See if you draw a triangle you'll have two angles or edges that are the same length. That is if you draw a standard triangle.
A triangular prism.... like the Toblerone chocolate box.... a triangle at each end. Label the angles A, B and C at one end and A1, B1 and C1 at the other end. Now, there are three rectangles - A, A1, B, B1 - A, A1, C, C1 - B, B1, C, C1
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.

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