There are no specific names for the faces.
A tetrahedron has 4 faces.
it has four faces
No and Yes A regular tetrahedron does not have any faces that are perpendicular to each other. (Regular in this sense means all edges are equally long - all faces are equilateral triangles)You can construct a irregular tetrahedron with two or three perpencdicular faces. To make such a tetrahedron with three faces perpendicular, simply cut the corner of a cube.
A tetrahedron has 4 faces. A "regular tetrahedron" has an equilateral triangular base with three equilateral triangles as sides coming up from it.

They don't have names beyond "the faces of the tetrahedron."
A tetrahedron or triangular pyramid.

A tetrahedron has four faces.
There are four number of faces in a tetrahedron.
A tetrahedron has 4 faces.
The faces of a tetrahedron are all triangular polygons. Specifically, a regular tetrahedron has equilateral triangles as its faces, while an irregular tetrahedron can have any type of triangle as its faces, but they will always be triangular in shape. Each tetrahedron has four triangular faces, four vertices, and six edges.
A truncated tetrahedron has eight 8 faces: 4 hexagonal faces and 4 triangular faces.

No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.
