A vertex can be the corner of a polyhedron in which case at least three edges meet at a vertex.
Three edges meet at each vertex.
Edges meet at a vertex.

No. For example, a cube is a polyhedron and 3 edges meet at each vertex.
A vortex is an area of circular fluid flow in fluid dynamics and no edges meet there. A vertex is a corner of a geometric shape and there can be two or more edges meeting at a vertex. There is no upper limit to the number of edges.
