What is non-polyhedron?
A polyhedron has "many sides" (by definiton). The only 3-D shape which does not have "many sides" is a sphere (which technically only have one "side").
What is non polyhedron?
A non polyhedron does not have these properties, maybe it is not closed, maybe one or more of the sides is a curved surface. In some branches of topology the sides of a polyhedron cannot intersect each other.http://wiki.answers.com/What_is_the_difference_between_a_polyhedron_and_a_non_polyhedron#ixzz185DDOyd9

It is not a regular polyhedron because it has unequal sides
Do 20 equal sides form a polyhedron?
No. A polyhedron is 3 dimensional. You have a regular polygon, regular because the sides are equal. If you asked about 20 surfaces, then it would be a polyhedron.
