None, but you can cut a cube into any number ≥ 2 of triangular prisms.
Triangular Prisms don't have any vertical edges
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.

If a triangular based pyramid has any right angles it has three. (Think of the corner of a cube). There are many triangular based pyramids that do not have any right angles.

14 if the triangular cross section has a right triangle, 12 otherwise.
None normally
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.
i be leave there are 5 edges on a triangular prism

Zero!
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 three rectangular faces which, between them, will have 4*3 = 12 right angles. It also has two triangular faces and these can have another 2 right angles. So the answer is 12 or 14, depending on whether the triangles are right angled or not.
