Strictly speaking, no. But, as the number of faces increases, polyhedra can approximate cylinders or spheres and so can "roll".
Each polyhedron is a kind of solid object. Some solid objects -- for example, a sphere or a torus -- are not polyhedra, but every solid object can be closely approximated with a polyhedra.
Zero. Points are zero dimensional objects. Straight lines are one dimensional objects. Planes and surfaces are two dimensional objects. Volumes and polyhedra are examples of three dimensional objects.

NO, but prisms are polyhedra. Polyhedra include a lot more shapes than just prisms.
Yes, any polyhedron with sides has vertices. The only three dimension objects which are not a polyhedra are spheres, spheroids, and ellipsoids.
No. A pyramid is a polyhedron. Many pyramids are polyhedra.
Polyhedra DBMS was created in 1993.
No. They have curved edges, so they can't be polyhedra.
Not exactly. A tetrahedron is a polyhedron. Many tetrahedra are polyhedra.
A pyramid will not roll and you cannot stack objects on top.
