A pyramid will have as many triangular faces as the number of sides its base has, plus one in the shape of its base. This means an octagon based pyramid has nine faces (eight triangular ones plus the octagon base).

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 two-dimensional figure. It has no faces but does have 8 sides.
