The 3D shape you are describing is a pentagonal pyramid. It has a pentagonal base with five sides, and five vertices where the triangular faces meet. The three rectangle faces are lateral faces that connect the triangular base to the apex of the pyramid. The pentagonal pyramid is a type of pyramid with a polygonal base and triangular faces.
rectangular prism
Yes, and three rectangular faces.
# of faces + # of edges + # of vertecies + 2
cylinder: 3 faces, 2 edges, no vertex
A cuboid is a 3D shape that can be a cube or a rectangle, both having 2 ends, 2 sides, and a top and a bottom face.
