Just use a different pid file for each daemon, perhaps
/var/run/ and /var/run/ .  Each daemon's
configuration file should specify the location of that daemon's pid
file.  Then, on the reasonable assumption that your CentOS init.d
functions work like my Fedora ones, it looks like each init script just
has to specify the appropriate pid file to killproc:

killproc -p /var/run/ rsync

The httpd init script has an example of this usage of killproc.

If you are unhappy with hard-coding a different pid file in each init
script: each script must know somehow which daemon configuration file it
is supposed to specify to rsync, so the scripts could parse the pid file
path out of the configuration file using sed.
