The quick answer to that is *yes*. You can, using GRUB, set up as many 
booting OSes as you like.

If you are going to have the different OSes boot off of different drives, 
then installation of the 2nd Fedora is straightforward. During the install 
you can simply tell it to partition the new drive and install everything on 
it. It will adjust the GRUB for you.

If you need to install it to an existing drive with no free partitions, then 
you'll need to repartition that drive. There are ways of doing this under 
Linux, but I would not recommend this approach for a neophyte.  "Partition 
Magic" under Windows apparently recognizes Linux partitions, but I have had 
no experience using it. Besides, I usually partition my drives right the 
first time! :-)
