No because a polygon is a plane figure. A football is a bit like a polyhedron, but all the faces of a polyhedron must be flat and, because of inflation, those of a football are not.
A cube is a solid figure called a polyhedron. A polyhedron is a solid figure with all flat faces. So a cone would be a solid figure but not a polyhedron becasue it has a curve and does not have all flat faces.
A polygon is flat shape with many sides
No, a cylinder is not a polygon. It is not a polygon because it has curved sides. In order to be considered a polygon, it would need to have flat sides. Also, a polygon is a 2 dimensional shape but a cylinder is a three dimensional shape.
No, a sphere is not a prism. A prism is a polyhedron with two parallel and congruent faces called bases, and all other faces are parallelograms. A sphere, on the other hand, is a three-dimensional geometric shape with all points on its surface equidistant from its center, with no faces, edges, or vertices. In essence, a sphere is a curved surface while a prism is a polyhedron with flat faces.
Nope - A polygon is a flat, 2-dimensional shape. A Polyhedron is a 3-dimensional shape.
Each face of a polyhedron must be a polygon: a flat surface bounded by straight lines. So, if any of the faces is curved, the shape is not a polyhedron.

It is a polyhedron.
If you're thinking of a polyhedron like one of the platonic solids, then I believe the faces are called "hedra" or "hedron" singular.
It is a face of the polyhedron
Start with the definition of a polygon. A polygon is a 2-dimensional (flat) surface all of whose boundaries are straight lines. Then, a polyhedron is a 3-dimensional (solid) object all of whose faces are polygons.
A face
a base
