You haven't done what you want. As squid.conf explains:

        You need to be aware that "always_direct deny foo" is NOT
        the same thing as "never_direct allow foo"

You really want

    never_direct allow all

You should have some messages in cache.log that explains
why Squid1 cannot select a parent.

You may want to make Squid2 or Squid3 a "default" parent
for Squid1.

        cache_peer squid2 parent 3128 3130 round-robin default

In this case Squid1 should try to contact Squid2 even if it
thinks Squid2 might be down.
