I am confident that there are several boot managers, likely one for each 
of those four OS's, that can find multiple bootable OS drives/ slices/ 
partitions and allow you to boot the OS of your choice.  But, my 
experience is that keeping them all running is an exercise in "infinite 
bug propagation"

I can afford US $45 mobile racks and US $20 SSD's.  My time and mental 
bandwidth are more valuable.

I would remove three of those drives and run one OS at a time.
