A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.
Yes.
A hexagonal prism is a polyhedron. Many hexagonal prisms are polyhedra.
A hexagonal pyramid.
Using Euler's Polyhedron formula V+F-E=2, givenF=14 and E=24, we have V=12.The polyhedron has 12 vertices.This assumes a genus-0 polyhedron. An example would be the hexagonal antiprism, a polyhedron having two hexagonal faces and 12 triangular faces.

errrrrh, I don't suppose you considered "a hexagonal prism" as an answer.

A polyhedron is a simply connected 3-dimensional shape whose faces are all regular polygons. A hexagonal pyramid is a special case in which one face is a hexagon and six faces are triangles.
