A cone. The base is circular and curved, and the tip of the cone is the vertex.

2 plane faces i curved face
A cone has one face - its base - and one edge but no vertices. Vertices only occur at the meeting of two straight surfaces.

2 plane faces, 1 curved face
The curved surface (or face) of the cone.
A sphere intersected by a plane, which could be a hemisphere. Alternatively, a cone, or a paraboloid.
A cone. The base is circular and curved, and the tip of the cone is the vertex.
A cone - although a face is generally taken to be a plane surface, not a curved one.
There is only 1 curved face!
