A polyhedron is a solid shape with many sides. The word "polyhedron" does not specify a number of sides.
A sphere as a polygon is a shape with three or more sides and a sphere has no sides
No. A five sided shape is a pentagon. A hexagon has six sides.
In my opinion, only if the shape has any of three characteristics A. shape has sides outside of the side naming convention (oct, poly, etc.) B. shape is unrecognizable remotely to anything or C. shape has no sides, but many curves.
A shape very close to a circle or an oval.
A shape with a million sides.

a shape with one million sides
A Hecatommyriagon has one million sides. Also megagon. See Sources and related links for more.
A one-million-sided polygon.
Maybe its the shape of cylinder which has 2 congruent sides and 1 rounded body.

It is a shape with 1 trillion sides
1 million.
A trapezoid
