A rhombus is a two dimensional figure while the concept of {faces, vertices and edges} is relevant to 3-dimensional shapes.
It is a cube.
A cube
A trapezium has 4 vertices and 4 edges or sides. It is a two dimensional figure so it has only one "face".
A hexagon is a plane (2-dimensional) figure with 1 face, 6 vertices and 6 sides (which may be called edges).

In geometry, a rhomboid is a cube like three-dimensional figure with faces that are called rhombi. It has 6 rhombi faces, 12 edges and 8 vertices.

An octagon is a 2-dimensional (flat) figure, with 8 sides and 8 vertices.
A three dimensional triangular figure with three faces and a base is called a triangular pyramid. It has four vertices, four faces, and six edges.
