If by using the word "coexist" you mean System 7 and A/UX must be at the 
same place or at the same time you are out of luck on both counts unless 
you have two Macs.  :-)

If you have enough disk, you can install *LOTS* of different versions of 
various operating systems, but you must choose which single one you want 
to boot.

It depends.  Will you have enough room on you hard disk(s)?

It depends.  Are all your disks Apple-issue?  If not, do you have 
partitioning software and drivers for System 7 and A/UX 2.0?

Here's what works for me:

I have a Mac IIfx with an Apple Internal HD80SC with standard A/UX 2.0 
partitions (includes a nominal System 6.0.5 boot partition).  I also have 
an external CDC Wren III with a Mac partition for System 7 and an A/UX 
user partition I created with SilverLining.

Using the control panel, I select the startup device that corresponds to 
which operating system I want to use -- System 7 or A/UX (via System 
6.0.5) -- and then restart.

Not a problem.
