A 3D cone has two faces: one circular base and one curved surface that extends from the base to the apex. The circular base is considered one face, and the curved surface wraps around to form the side of the cone. Thus, in total, a cone has two distinct faces.
A cone !
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
The 3-D shape with one edge, two faces, and one vertex is a cone. It has a circular base (one face) and a curved surface that tapers to a point (the vertex). The edge is the circular boundary of the base.

A normal cone has a circular face as its base, and a slanting surface which goes from the circumference of this face to the vertex. So it has two faces. Mathematicians also refer to the infinite equivalent as a cone. This could be considered as a 3-d shape with one face.

An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Several of these may be considered as octahedron cone and the answer depends on which particular shape you have in mind.

None, its a sphere

None. A triangle is a 2-D figure, not a 3-D figure. Therefore, the concepts of faces and bases do not apply to it.
A 3-D cone would act as the ice cream cone and a 3-D sphere would act as the ball of ice cream.
