A prism. The name of the prism usually reflects the polygonal shape of the bases eg triangular prism or rectangular prism.
prism
A triangular prism.
Obviously some kind of PRISM.
A three-dimensional figure formed by six parallelograms is called a Parallelepiped. A cube is one example and leads to the alternate definition of a polyhedron with six faces, each of which is a parallelogram.The opposite sides are in parallel planes.
A cylinder
The figure would be a prism. However, congruent polygons in parallel planes are called bases.

A prism
It need not be. A sphere, for example, has no rectangles nor polygons and no parallel planes either.
A cylinder
Yes. The opposite ends of any right prism consists of two congruent and parallel faces. Two planes are parallel if the vertical distance between them is always the same.
The given description fits that of a cylinder
A cylinder is best described as congruent on parallel planes or discs.
