A rhombus is a two dimensional figure while the concept of {faces, vertices and edges} is relevant to 3-dimensional shapes.
There is no such object. A decahedron is a 3-d object with 10 faces whereas a dodecahedron is a 3-d object with 12 faces. Each of them can have different numbers of edges.
Not sure what a decagonal is. Since the question refers to faces, edges and vertices, it may be assumed that the object in question is 3-dimensional. A decagon certainly is not, so decagonal cannot be a mistaken name for a decagon.
No. I'm a piece of paper.
Edges are found in 3-dimensional objects. Then vertices are the corners and edges are the lines formed where two faces meet. In this case, sides usually refers to the faces.
A rectangular prism is solid 3-dimensional object which has six faces that are rectangles. It has 12 edges and 8 vertices.

traingle * * * * * No. Apaprt from the spelling, a triangle is a 2-dimensional object. There cannot be a 3-dimensional polyhedron with the specifications of the question because the Euler characteristic requires that Faces + Vertices = Edges + 2 and that clearly is not the case here.

A 3 dimensional box or cube shape.
Rectangles are plane (2-dimensional) polygons. Only solid (3-dimensional) polyhedrons have faces.

a tetrahedron (aka three dimensional triangle)
An octahedron is a polyhedron with eight faces, twelve edges, and six 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.
