It depends on the uses the lens are going to be put to. A lens may have a convex front and a flat back, or a convex front and a concave back, or even a convex surface on both front and back. Or even concave on both the front and back.
Concave means bowed inwards.
Convex means bowed outwards.

How many flat and curved surfaces pyramid?

A pyramid has a combination of flat and curved surfaces, but it typically consists of flat surfaces only. Specifically, a pyramid has a base that is a polygon (flat surface) and triangular faces that connect the base to a single apex, all of which are flat. Therefore, a standard pyramid has no curved surfaces. The total number of surfaces depends on the number of sides of the base polygon; for example, a square pyramid has five flat surfaces (one base and four triangular faces).
