ACL verification _wastes_ CPU only if you do not need those ACLs to be
verified. If that is the case, simply remove them. In all other cases,
the CPU cycles are not wasted but spent on doing useful work.

Sorry, I do not follow your logic. Restricting some work such as ACL
processing to one CPU is more likely to make the "balance" worth, not
better, right? Why do you want to do that?
Is your current CPU core balance a bottleneck? Have you solved all other
Squid-related problems? If you cannot answer "yes" to both questions,
then you are most likely doing what some call "premature optimization".
Focus on removing what you think is the performance bottleneck instead.
If you do not know where the bottleneck is, then focus on finding it.
Meanwhile, until you reach a very good level of Squid understanding, it
is best to use the same squid.conf for all Squid workers. While certain
exceptions to this rule of thumb are technically possible, random
attempts at giving different workers different configurations will
usually result in a broken Squid.

Because you have not configured visible_hostname for any of your Squid
processes except process #4.
BTW, you also have not configured any access rules for most of your
workers which will result in them denying all requests they get.
HTH,
