You have previously mentioned that you are running Ubuntu.  In which
case it should be the same as my Debian.  Just install the other
versions.  They will install side by side without conflict.

  apt-get install emacs24
  apt-get install emacs23
  ...

Or use one of the varients.  I am partial to emacs24-lucid for
graphical desktops and emacs24-nox for headless servers.
