An octahedron is a 3d shape that has eight faces. An octahedron is made from equilateral triangles, with four points meeting in one spot called a vertex.
Pentagon
cube 8
Pyramid
The numbers do not satisfy Euler's characteristic so there can be no such polyhedron.
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.

There are infinitely many shapes that have ten faces.
The numbers do not satisfy Euler's characteristic so there can be no such polyhedron.
