if you wanna allow few Lan user to use squid then find the ip address of those users and
Do the following in your squid.conf
-----------------------------------------------------------------------------------------------
acl validuser src 192.168.0.4/255.255.255.0 #Line 1
acl rangeofvaliduser 192.168.0.6-192.168.0.20/255.255.255.0 #Line 2

http_access deny all
http_access allow validuser
http_access allow rangeofvaliduser
----------------------------------------------------------------------------

Now in line u can give the ip of a specific user which u wanna give access to net.
And from Line2 you can specify a range of user who are allowed to connect internet thruogh proxy

Also here validuser and rangeofvaliduser are the user defined variable assigned to the range of ip address or a specific ip address.
