It is a polyhedron with two congruent faces: nothing more, nothing less. That can change if several additional conditions are required of the polyhedron.

7 faces
There cannot be such a polyhedron since it does not satisfy Euler's criterion.
The answer is a polyhedron
6
A pentagonal pyramid.
No, they are the faces of the polyhedron.
