I think it's only a matter of passing the right config file on the
rotate call using the -f option so the temporary app can send the rotate
to the right PID.

I'd merge the two configs together too so they are handled the same way
no matter what.

/etc/logrotate.d/squid:

#
# Logrotate fragment for squid (both 1 and 2).
#
/var/log/squid/*.log /var/log/squid2/*.log {
         daily
         compress
         delaycompress
         rotate 90
         missingok
         nocreate
         sharedscripts
         postrotate

  test ! -e /var/run/squid1.pid || /usr/sbin/squid -f
/etc/squid/squid1.conf -k rotate

  test ! -e /var/run/squid2.pid || /usr/sbin/squid -f
/etc/squid/squid2.conf -k rotate

         endscript
}
