  There's a short introduction to doing this type of calcualtion
using the VMD scripting interface in the VMD user's guide, try out
the examples shown therein, and we can help if you have specific
questions not coverdd in the documentation:

Of course, the coordination number of A atom can be calculated with the criterion: if the distance between A and an atom is shorter than a distance value (say 2.2, 2.3 or 2.4 or 2.5 angstrom), then we can consider the atom coordinating to A.
