OK but why do it the hard way, instead of putting one of them in a VM? Or better, Fedora 20, and put two CentOS and another Fedora each in their own VM? In that case you don't have to deal with the esoteric, user hostile, world of bootloaders on Linux. You can just get to booting multiple OS's. And they boot faster.
The only reason for dual booting I can think of is expressly to learn about the challenges of getting bootloaders to do dual booting.

It's a lot more than that I can assure you. It took me more time than I care to admit, and if I could get that time back from the life blood sucking experience it was, I'd probably do that.
remove "hidemenu" so you can see the menu, and duplicate the two entries, changing just the one thing that matters which is the menu entry name, and the root. You do not need separate swaps either.

Not really. It's the domain of bad documentation designed for developers, not users. I learned what I learned via immense suffering and blunt contact.
