You can share partitions between distros, but not the system directories.
Examples: /home /pub /www, those types of partitions that Linux doesn't use to run.
If you don't mind losing your present installation, here is what I suggest for a home box multiboot:
Windows partition if used installed on first primary partition of primary master hard drive
My distros need / partitions of between 2 and 2.9 gig. I like to assign 3.5 - 5 gig (tons of games installed) for each distro's / partition. Make a separate / partition for each distro you would like to use/try.
swap - 128 MB max (unless you are running a heavily accessed server)
If you use a filesystem such as reiserfs, jfs, xfs for /, you will probably need a /boot partition. Distros can share this, but make sure you understand your bootloader and can point stuff to the right place if you use this.
I recommend ext3 filesystems for newbie beginners for simplicity.
The rest of the drive, put in /home.
On the installs after you have something in /home you don't want to lose, just choose not to format that partition during the install of subsequent distros.
