a sphere
How about a sphere
Any ellipsoid, including the sphere.
A pyramid, as well as any other solid figure bounded by plane polygons or faces, is a polyhedron.
The solid figure that has 2 flat surfaces and 0 vertices is a cylinder. A cylinder consists of two parallel circular bases (the flat surfaces) connected by a curved surface. The bases do not have any vertices, as they are continuous curves.
It is not any kind of simply connected solid figure because it does not satisfy the Euler characteristic which requires thatFaces + Vertices = Edges + 2It is not any kind of simply connected solid figure because it does not satisfy the Euler characteristic which requires thatFaces + Vertices = Edges + 2It is not any kind of simply connected solid figure because it does not satisfy the Euler characteristic which requires thatFaces + Vertices = Edges + 2It is not any kind of simply connected solid figure because it does not satisfy the Euler characteristic which requires thatFaces + Vertices = Edges + 2

A sphere.
That's a Sphere not Cylinder cuz it had flat Circles Above and
Sphere
An ellipsoid.
Any ellipsoid, including the sphere.
An octahedron is any solid shape with eight flat faces.
It is a sphere
Not aware of any solid figure with 2+3=5 rectangular faces or bases.

There are many such shapes: a sphere, ellipsoid, toroid all have no flat faces. Any one of the intersected by one plane will have one flat face, if intersected by two planes, there will be two and so on. Amongst polyhedra, only a tetrahedron (or triangular prism) fas fewer than 5 flat faces.
