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.

A triangular prism has two right angles. Each end of the prism, which is a triangle, has one right angle. The third right angle is formed where the two rectangular sides meet. So, in total, a triangular prism has two right angles.
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 has 6 verticies
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 prism has a total of nine angles. Each of the two triangular faces has three angles, totaling six angles. The three rectangular faces each have one right angle, adding three more angles. So, the total number of angles in a triangular prism is 6 + 3 = 9 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.
