Octagon
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 3D shapes that have all their faces equal to their base are known as regular polyhedra. Specifically, these include the tetrahedron (4 triangular faces), cube (6 square faces), octahedron (8 triangular faces), dodecahedron (12 pentagonal faces), and icosahedron (20 triangular faces). Each of these shapes features congruent faces that exhibit symmetry.
The numbers do not satisfy Euler's characteristic so there can be no such polyhedron.

Each of these shapes features congruent faces that exhibit symmetry.
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.
