That could be a pentagonal pyramid.
There is no shape with only four triangular faces and five vertices. If there is also a quadrilateral face then it is a quadrialteral based pyramid.
A dodecagon is a plane shape and so has only one face. It has 12 sides and 12 vertices.
Your question is inconsistent on its face. You asked "What shape has zero faces . . . . . and has only one face." I'd say that nothing could ever meet both of those requirements. They are ... how you say ... 'mutually exclusive'.
There is no such shape. The only convex shape that has four faces is a tetrahedron, and that has four vertices, not 5.
Since the number of sides and vertices is different, it cannot be a 2-dimensional shape. The only 3-dimensional shape with 4 vertices is a tetrahedron and that does not have 6 sides. Consequently, there is no such shape.

A pentagonal is pentagon. As pentagon is 2D shape or object so it is having only one face.
The shape that has no vertices and is round is a circle. The circle is the only shape that does not have vertices.
There can be no such shape. A hexagon is a 2-dimensional shape and so has only one face, six sides and 6 vertices.

A very common shape: the triangle. It is a flat plane that has only 1 face and always has 3 vertices or corners.

I believe that the only polyhedron or polygon that own all of these features to be a sphere
No vertices (0). a heart shape is not a polygon shape, only polygon shapes have vertices.
An octagon, a cube, a seven-sided pyramid.
