A hexagon has 6 sides and 6 vertices.
a shape with 7 vertices
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.

Shape has fewer than 6 sides
a cube i guess
A pentagonal pyramid (5 sides and 1 base) has 6 faces, 6 vertices, and 10 edges (5 between the sides and 5 with the base).
There can be no such shape. A hexagon is a 2-dimensional shape and so has only one face, six sides and 6 vertices.
If a six sided hexagon has 6 sides then it follows that it will have 6 vertices
