Sorry. I do not understand what you are talking about here.

Proxy username & password are cached by the browser, not by Squid. If
the user starts another browser then he has to authenticate again unless
he has provided his username+password to his browser by some other means
than manual authentication.

With Squid 2.0 detailed access restrictions are possible, but it
requires a large amounts of ACL lists.

acl host_scratchy src scratchy
acl host_itchy src itchy
acl user_joebloggs user joebloggs
acl user_finbarr user finbarr

# Allow joebloggs from itchy
http_access allow user_joebloggs host_itchy
# Allow finbarr from scratchy
http_access allow user_finbarr host_scratchy
