It is a pentahedron. One example of an irregular pentahedron is the 4-sided pyramid.
It could be a pyramid with a quadrilateral base or a triangular prism. There are, of course, other related shapes that it could be.
A 3d shape with 5 faces can be a square pyramid
An example of a common five faced three dimensional shape is the square pyramid. There are no three dimensional shapes with five edges.
