I set up a machine that booted 4 different Centos installations the other day.
All you have to do is tell the installer that you want to do a custom
partitioning scheme, then point it to /dev/sda or /dev/sdb or whatever, and
tell it to use X amount of the space on that drive. Don't install the boot
loader on anything but the first install, then add the new partitions/setups
manually to grub.conf as you create them.
I found it easiest to not use a /boot partition though there is probably a way
to do it with one as well.
Here is the grub.conf that I ended up with on my 4-way booting machine:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd0,0)
# kernel /boot/vmlinuz-version ro root=/dev/sda1
# initrd /boot/initrd-version.img
#boot=/dev/sda
