Q:

What is the maximum size that an vim or emacs can open & edit?

I would like to know what is the maximum size that an vim or emacs editore can open & edit

A:

The documentation just states this:

Maximum file size 2147483647 bytes (2 Gbyte) when a long integer is 32 bits. Much more for 64 bit longs. Also limited by available disk space for the |swap-file|.

so "much more" will most likely run into your hard drive limitation since it goes to exabytes of alocatable size.
