8 lateral faces and a base
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
One side will be a square. It is the base. The lateral sides are triangles.
The given description fits that of a triangular based pyramid which has 4 faces, 6 edges and 4 vertices
That object would be called a triangular pyramid, also known as a tetrahedron.
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).
Lateral faces are the number of faces excluding the base. Since the square is the base, the other 4 sides will each be touching a lateral face to form a square pyramid (or it wont be a pyramid). So, there are 4.

Lateral Face - In a prism, the faces that are not bases. In a pyramid, faces that intersect at the vertex.
9. 8 lateral faces and a base.
The lateral face for a prism or pyramid is any edge or face which is not part of a base.
