According to my calculations, I am a complete nerd, and the answer to your question is 0, there are no 90 degree angles in an octagonal prism.
A octagonal prism has 32 right angles!!!!!
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.
The solid is a cuboid, or "right rectangular prism" in which all angles are right angles. It is a box shape, or regular hexahedron.
It depends on the prism. A prism that has a regular pentagon as base but is not a right prism has no right angles. At the other extreme, consider a right prism whose bases are pentagons that resemble a child's drawing of a house (square with a triangle roof). If the angles of the roof triangle are 90-45-45, the prism will have 22 right angles.

i think a octagonal prism has 32 right angles! :)

Prisms with any number of sides can have perpendicular faces. Often both end faces are perpendicular to the length. In the case of a REGULAR octagonal prism, there will be four pairs of parallel faces, where each face of a pair will be perpendicular to the two faces of one of the other pairs. There is not much that can be said with certainty about an irregular octagonal prism.
A rectangular prism has six faces; each face has four right angles. There are 24 right angles in all.
A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.
24.
A pentagonal prism has 5 faces, with each face having 5 vertices. Each vertex connects two adjacent faces, forming a total of 10 right angles around each vertex. Therefore, a pentagonal prism has a total of 50 right angles.
There are 24.
