Adding to what Kittenono said, an octagon is a two dimensional shape which only has length and width. A polyhedron is 3 dimensional which has length, width and height.
octagon
Octagon if you're talking polygon but a rectangular pyramid has 8 edges.
If it's a polygon (2 dimensional) then an octagon. If it's a polyhedron (3 dimensional) then a rectangular prism (or a cube).
No, they are the faces of the polyhedron.
An octagonal cupola is a type of polyhedron. Faces: 18 Edges: 40 Vertices: 24 The octagonal cupola is composed of one octagon, one hexadecagon, eight rectangles, and eight triangles.

As far as I am aware, there is no polyhedron (3-d figure) whose faces are all octagons. As far as I am aware, there is no polyhedron (3-d figure) whose faces are all octagons.

The definition of polyhedron. If it was not faceted it would not be a polyhedron.

yes it is a polyhedron
They are the faces of the polyhedron.
No, a cubiod is not a polyhedron but a cuboid is.
For planar shapes, an eight sided polygon (also simply octagon) is any shape with eight straight sides it does not have to be equilateral (same length on all sides) or equiangular (same angle on all sides) as the regular octagon is.If you are talking about 3 dimensional shapes the terms are polyhedron & octahedron
