No, there are many different types of pyramids. To give a real-life comparison, the Egyptian pyramids are square pyramids, and have 5 faces. Triangular pyramids have 4 faces. (Count the base as one face) A pentagonal pyramid would have 6 faces. (Five on each side, plus the base) A hexagonal pyramid would have 7 faces, etc. (One for each side base + the base's face)
5 faces 8 edges 5 vertices
7 faces 12 edges 7 vertices
