If the 777 permission does not work (like you said it dont) then it is
*definitely* something right down in the kernel or driver levels, not a
Squid or chown/chmod problem.

You seem to be still focussing on chown/chmod alone (filesystem level)
and not taking SELinux permissions (kernel level) into account - despite
having been told to check them several times already.

Do this:

* erase cache_effective_group from your squid.conf

* comment out the cache_dir /var/spool/squid2 lines in your squid.conf

* run the command line and fix any ERROR or FATAL that come up:

  squid -k parse

* run command line (dont worry if it fails or says already a member):

  adduser squid squid

* run the command lines:

 chmod -R 777 /var/spool/squid2
 rm -rf /var/spool/squid2/*
 chmod 755 /var/spool/squid2
 chown squid:squid /var/spool/squid2
 test -x /sbin/restorecon && restorecon -R /var/spool/squid2

* un-comment the cache_dir /var/spool/squid2 line in squid.conf

* run these command lines:

 squid -z
 test -x /sbin/restorecon && restorecon -R /var/spool/squid2
 squid -k check
