A tetrahedron is one such, so is an octahedron.

A polyhedron with the fewest number of faces is a triangular pyramid - it has four faces including the base.
Yes because it has many faces which is the meaning of a polyhedron

hexahedron ex:cube, triangular dipyramid, triangular deltohedron, pentagonal pyramid
A regular polyhedron has equal size faces as in the case of a tetrahedron which is a triangular base pyramid that has 4 equilateral triangle faces.
I am pretty sure it is a triangular prism!
