That would be a triangular pyramid.
A triangular prism can have a square or triangular base, but faces are normally triangles. (I think)
It depends on the shape of the base, but yes it has at least 3 triangular faces!(yes)
A tetrahedron.

Triangular Pyramid
The shape you are describing is a triangular pyramid. A triangular pyramid has a base that is a triangle and three triangular faces that meet at a single point called the apex. The base of the pyramid is a rectangle, which is a quadrilateral with four right angles. The triangular faces of the pyramid connect the vertices of the base to the apex.
