Yes. A polyhedron is a geometric shape with flat surfaces and straight edges, so a a pyramid with a rectangular base qualifies as a polyhedron.
It is however not a regular polyhedron, which would require all the faces to be the same shape and size. To change your pyramid to a regular polyhedron you'd have to turn it into a tetrahedron.

What polyhedron has 8 edges?
Octagon if you're talking polygon but a rectangular pyramid has 8 edges.
What are the flat surface on a pyramid cube or rectangular prism called?
faces every polyhedron has one
What are the polygons that form a polyhedron?
Any. You can have a triangular pyramid (tetrahedron), a rectangular one, a pentagonal one, and so on. Similarly, you can have a triangular prism, a rectangular prism, and so on.
What are three different geometric solids that have at least one rectangular face?
A polyhedron of 5 or more sides can always be found that has a rectangular face. So three shapes are:a pentahedron (rectangle based pyramid),a hexahedron (cuboid),a heptahedron (pentagonal pyramid).
Is the pyramid a polyhedron?
Yes.
