A vortex is a form of rotating fluid flow: for example a whirlpool. A vertex, on the other hand, is a point where lines meet. There can be two or more lines meeting at a vertex: there is no limit to how many. For example, the apex of a pyramid whose base is a polygon with n-sides, will be a vertex where n edges meet (for any integer n).
Three edges meet at each vertex.

12 4 edges on each end (8 total) where the rectangle side faces meet the square end faces and 4 edges the rectangular faces meet each other.
No. For example, a cube is a polyhedron and 3 edges meet at each vertex.
Often 3, but it depends on the shape.

A vertex can be the corner of a polyhedron in which case at least three edges meet at a vertex.
A pentagonal pyramid has 10 edges. 5 that meet with the base (because its a pentaon) then one from each vertex of the base that all connect at the top. As explained above actually it has 10 edges.
