Depends whether you installed whatever OS with or without NOOBS or BerryBoot :!:

Yes, but .... not easily!

install just realy means copy files , so for example you can make a 2nd " install " of the os you all ready have by making a second copy of the files in another partition ...

Then !
You just need to change the boot config file called cmdline.txt to use/boot the 'new' root file system copy (* you dont need to change the kernel in this example case, but for another OS you might ! )

Hope thats as clear as mud .

When you install any OSes with NOOBS, it normally expands each OS equally to fill the available space on the SD card.
You can prevent this by manually editing the json files if you are installing locally, but no chance if you are installing from the internet (ie.. something other than Raspbian)
And even if you were able to leave space on the SD card for your third OS, NOOBS wiped the whole SD card whenever you want to re-install any one of them.
So my advice would be to install all 3 OSes from the start. You could manually replace the third OS with a different one later if it takes up a similar amount of space and you know what you are doing.

With NOOBS you can NOT do that.

Don't know about berryboot, I prefer to spend a fiver for another SDCard, it's easier.
