Depends heavily on where in the body/brain the neurons are
located.  An average for all the neurons in the brain is about
1,000 connections.  But individual neurons can deviate from
that number by orders of magnitude.

Yes.  For some connections, there is no reason for them to
change, and a change could, in fact, be catastrophic (consider
input/output connections).  For others, change is necessary
for learning/memory.
