Depending on what your CD is, the easiest way is to copy the patches off into /tmp, unzip them and cd to /tmp/<patchdir> (where they were unzipped to) and look for a file called install_cluster and run that. That will be the case if it is a 'Sunsolve CD'. You may need, depending on what patches are included, to bring the server down to single user to install.
If they are just a 'random' bunch of patches then you may have more problems in getting the order in which to install them correct - redoing the patchadd command until all that will install are installed is one, really, REALLY, inelegant way of doing that. Failing that, looking through all the readmes to find out any pre-reqs will be required.
