There is no regular polyhedron with 9 vertices There are many other defined polyhedra with 9 vertices, though:
elongated square pyramid (cube with a square pyriamd on top)
gyroelongated square pyramid
triangular cupola
triaugmented triangular prism
tridiminished icosahedron
It's hard to describe the shape of some of these. See the related links below for pictures.

What polyhedron have some a face but no edges and no vertices?
A polyhedron must have at least 4 faces, at least 4 vertices and at least 6 edges.
What type of polyhedron has 9 faces 9 vertices and 16 edges?
an elongated square pyramid- here is a website with pictures(http://en.wikipedia.org/wiki/Elongated_square_pyramid )
Which polyhedron has 12 vertices's and 18 edges?
eighthedron eighthedron
Polyhedron has 10 vertices and 10 edges how many faces?
Such a polyhedron cannot exist. According to the Euler characteristics, V + F - E = 2, where V = vertices, F = faces, E = edges. This would require that the polyhedron had only two faces.
How many vertices are in a polyhedron?
Any integer that is greater than 3.
