A (genus-0) polyhedron must satisfy Euler's formula:
V + F - E = 2.
Setting V, E, F equal to the same value, say, X, we get
X + X - X = 2
X = 2.
A solid with two edges, vertices and faces is called a "digonal hosohedron", but it is not usually considered a three-dimensional figure, in euclidean space.
A rhombus is a two dimensional figure while the concept of {faces, vertices and edges} is relevant to 3-dimensional shapes.
A trapezium has 4 vertices and 4 edges or sides. It is a two dimensional figure so it has only one "face".
It is a cube.

A hexagon is a plane (2-dimensional) figure with 1 face, 6 vertices and 6 sides (which may be called edges).

A rectangular prism and a cube! :)

It is the intersection of two planes or the line joining two vertices.

Triangular Prism Triangular Prism 5 faces, 9 edges 6 vertices
An octagon is a 2-dimensional (flat) figure, with 8 sides and 8 vertices.
According to the Euler characteristic, the number of faces, edges and vertices are related by: V - E + F = 2 for ANY convex polyhedron. If V = E then F = 2 faces. Also, E = F requires V = 2 vertices. No such figure exists.
