cone
A cone has 1 face, 0 edges, and one vertex. The face is the circular flat area. The cone can roll, so it has no edges. Edges have to be straight. The vertex is the pointy thing opposite to the face.
a cone
An infinite cone.
A cone. The base is circular and curved, and the tip of the cone is the vertex.
Yes, the point on the cone is a vertex.Typical math textbooks define a cone as "A solid figure with one circular face and one vertex." So yes, there is one vertex.

One possible answer is an infinite cone. Spheres have one face but no vertex. No physical 3-D shape can have a vertex without having more than one face (a real cone typically has two: side and bottom).
