A regular pentagon does not have any parallel sides. In contrast, a pentagonal prism has two parallel and congruent bases.
Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.
O par ell lines and no congruent lines
There are 56 pairs of congruent angles.

the sphere doesn't have a base because it's all round

There are infinitely many such polyhedra. A regular dodecahedron, for example.
Yes, a trapezoid has two bases. They are the parallel lines on the top and bottom. Parallel lines look like this =
