Octahedra. But there are 257 different kinds. Some of the more common ones are:
heptagonal pyramid.
hexagonal dipyramid.
hexagonal prism.
truncated tetrahedron.
tetragonal trapezohedron.

Pyramid
cube 8
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.
2 solid shapes together have 8 faces, 12 edges 8 vertices

Pentagon
Pyramid
cube 8
Shapes that have more than six faces include polyhedrons such as the cube, which has six square faces, and the octahedron, which has eight triangular faces. Additionally, shapes like the dodecahedron have twelve pentagonal faces, and the icosahedron has twenty triangular faces. These shapes are examples of polyhedrons with more than six faces.
No, two dimensional shapes do not have faces
A quadrilateral based pyramid
There are infinitely many shapes that have ten faces.
The numbers do not satisfy Euler's characteristic so there can be no such polyhedron.
5 faces
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
