The answer depend on the truncation but assuming it is by a plane parallel to the base, the truncated tetrahedron is like a triangular prism (except that one base is smaller than the other). It, therefore, has 5 faces, 6 vertices and 9 edges.
A truncated tetrahedron.
it has 12 vertices
There are four number of faces in a tetrahedron.
A tetrahedron has 4 faces.

A truncated tetrahedron.
A truncated Octahedron has 36 edges.
pentahedron examples: tetrahedron with one truncated corner, square pyramid
There are infinitely many such shapes. A tetrahedron, truncated hexahedron, icosahedron, pyramids, anti-prisms are some examples.
