You can call it a hexahedron. A hexahedron is any polyhedron with 6 faces. A special kind of hexahedron having 6 faces made of congruent squares is called a cube.

In general, any 10-sided polyhedron is called a decahedron. With 10 regular triangles for faces, you may have a pentagonal bipyramid.
7 faces
There cannot be such a polyhedron since it does not satisfy Euler's criterion.
Its a platonic solid :)
