A prism has two parallel and congruent bases in the shape of polygons. Example - a cereal box (is rectangular prism). The top and bottom are rectangles(a polygon). They are the same size and shape (congruent) and also parallel. A cube (think of six sided dice) is a special rectangular prism. Imagine a a box where the top and bottom are triangles (of the shape size and shape). This is called a triangular prism.
No. Congruent means the same shape and the same size. Two perfect circles would be the same shape but they might not be the same size.
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.

prism
parallelogram, because if the two bases are congruent and parallel then the sides will also have to be parallel, so it is a parallelogram
Triangle
It is a cylinder
When a base is congruent it is the same shape and size, and parallel is when they will never touch. Therefore, on a square the top and bottom are congruent parallel bases. Some other examples are: Cylinders, rectangular prisms, and of course parallelograms.
the sphere doesn't have a base because it's all round
No, its a triangularprism

Prisms are classified according to the shape of the two congruent and parallel plane shapes which form its bases.
