Hello and welcome to LinuxQuestions,

You are asking a lot in one thread

Although LinuxQuestions is in my personal opinion all about helping out other Linux users, it is not a place to get step by step guides. You'll have to put in some work of your own and when encountering problems then I'm sure someone here can offer a solution.

Your first starting point and in my opinion a pretty good one is Google.

DNS
Squid
YUM

In the lists that gave those queries are some pretty easy to follow guides. Again, if you have problems following one of them, let us know.

Kind regards,

Eric
