REQUIRED is just a wildcard to match any valid user.
proxy_auth is just a ACL like the others, taking a list of valid
usernames this acl name matches (like dstdomain takes a list of
domains, src a list of ip addresses/networks etc..).

A acl name of your liking. Is what connects http_access to the list of
usernames in the acl... has no meaning outside your sqiud.conf.
The names foo and bar are commonly used in examples to indicate
"something of your liking", inteneded to be replaced by a name you
find suitable for your situation.

No different than "bar". Both are just names of the acl definitions in
the example, to separate the two from each other.
Your squid.conf could just as well read
acl all src 0/0
# Allow VIP persons access all the time
acl vip_users proxy_auth lisa sarah frank joe
http_access allow vip_users
# Other users may only browse during daytime
acl daytime time 08:00-17:00
acl all_users proxy_auth REQUIRED
http_access allow other_users daytime
# Deny all else
http_access deny all
The above is 100% identical to your configuration, except for changes
in internal names of the acls and the addition of some comments
explaining what the rules does..
Regards
Henrik
