An octagon has only one face as it is a 2 dimensional figure. It has eight edges.
An octagon doesn't have any faces: faces only apply to 3-dimensional objects. If you meant edges, or sides, an octagon has eight. If you meant an octagonal prism, they have ten faces.
An octagon has 8 edges
An octagon has 8 sides or edges
The question is ambiguous. An octagon is a 2-dimensional shape with 8 edges and 8 vertices. Does a 3-D octagonal shape mean one with 8 edges or 8 faces or vertices, or faces which are 2d octagons?

An octagon, (2D) has one face, zero edges, and eight sides.
An octagonal pyramid has 9 faces and 14 edges. The base of the pyramid is an octagon with 8 faces, and the pyramid itself has an additional triangular face. The edges consist of the edges of the octagon base and the edges connecting the base to the apex of the pyramid.
An octagon doesn't have any faces: faces only apply to 3-dimensional objects. If you meant edges, or sides, an octagon has eight. If you meant an octagonal prism, they have ten faces.
An octagon is a 2-dimensional (flat) figure, with 8 sides and 8 vertices.
An octagon has 8 sides with 8 vertices and one flat face
An octagon has 8 edges
An octagon has 8 sides or edges
An octagon based pyramid.

There is no 3d shape made up of octagons. An octahedron can be one of several different shapes - but without ANY octagonal faces. For example, A hexagonal pyramid (8 faces, 18 edges, 12 vertices) A heptagonal pyramid (8 faces, 14 edges, 8 vertices) A quadrilateral dipyramid (8 faces, 12 edges, 6 vertices)
