| 1. PATH is presumably the shell variable $PATH ?

Yes the list of directories to search to find the command you entered.

| 2. What is LD_LIBRARY_PATH and how do I set it?

same way and style as PATH.  It is a list of directories to search
for to find the extra libraries a command needs.

NOTE this is DYLD_LIBRARY_PATH on a MacOSX,  just to be different!

| 3. Will this be doable using your method outlined here: 
http://www.imagemagick.org/Usage/api/#building

That is for building a RPM package for installation.  The package
manager will insist only one package for a particualr bit of software
is installed.

My note for multiple versions are much more RAW and are located in
  http://www.cit.gu.edu.au/~anthony/info/graphics/imagemagick.hints

Much of the later info in this file pre-dates the development of IM
examples.
