A vertex is the name of a corner on a solid where three or more faces meet (plural = vertices).
The solid you are describing is called a cylinder. It has two circular faces, one curved face, and no vertices.
Triangular prism
Well, a triangular prism has 5 faces and 6 vertices, but it has 9 edges. So I'm not sure.

No. Every solid shape has at least one face. The closest you will get is a sphere, which has no edges or vertices, but it still has a face.
Trapezium, or triangular pyramid * * * * * A triangular pyramid, yes. But not a trapezium since that does not have four triangular faces.
There is not a polyhedron with the given number of faces, edges and vertices.
a cube has 8 vertices.
square-based pyramid
6 vertices, 2 triangular faces, 3 rectangular sides, 9 edges
