They have 6
An octahedron shape is one which has 8 faces. Since it is a prism it must be a hexagonal prism (2 hexagons and 6 rectangles = 8 faces). And a hexagonal prism has 2*6 = 12 vertices.
In 2D, there are 6 vertices in a hexagon; there are 36 vertices in 6 hexagons. In 3D, it doubles up to 12 vertices.

They have 6
A 6 sided hexagon has 6 vertices and so 3 hexagons will have 3*6 = 18 vertices
Rectangles have 4 vertices.
Add one to a hexagons number of vertices

An infinite number, if you cut them small enough.
They can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons. It has 8 faces and can have 6 to 12 vertices.
A rectangular prism is a solid (3-dimensional) object which has six faces that are rectangles. Such a shape has 8 vertices.
A hexagonal prism doesn't have any triangles. There are two hexagons and 6 rectangles.
