There are only 5 regular polyhedra: those with 4, 6, 8, 12 and 20 faces. If you know of 7 polyhedra there may be a Fields Medal (the Nobel prize for mathematicians) for you!
A twelve-faced shape is a dodecagon, also known as a dodecahedron.
They are all polyhedra with 12 edges.
Polyhedra are named by the number of faces they contain. The names are based on Classical Greek. Over time, some polyhedra have become known by common, non-Greek names, i.e. a regular hexahedron is commonly called a cube.
