A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n ≥ 3.

A square pyramid. One base, and 4 sides.
Five faces (it is a 3 dimensional shape). A four sided pyramid is a pentahedron. (penta- means five, -hedron means sides)
I would say a square-based pyramid but there are many 3 dimensional shapes with 5 sides.* * * * *The generic name is a pentahedron.
3 sides
A pyramid does not need to have any equal sides. A REGULAR pyramid has as many equal sides as the number of sides on the base. So, a triangular pyramid (tetrahedron) will have 3 equal faces, a square based pyramid will have 4, etc.
