Is there be any extra extreme charges ?

I am on the AT&T Unlimited Elite plan if it matters.

The amount of data bandwidth needed for voice over an IP network is really low compared to website surfing, let alone listening to music or watching videos. But does AT&T charge extra for wifi calling? Good question, but I doubt it because usually you are reducing network load by using someone's internet connection.

Also when I enter my address is it only for my phone or everyone's phone on a plan with 3 other people, 4 total ?

OK, let me explain. When you either initiate a wifi call or take a call via wifi calling you are connected to an ambiguous IP network, but the call traffic is transmitted to a traditional telephone carrier. This isn't a problem if both parties are in your carrier's local area of coverage, but if you are in a land that doesn't have direct AT&T network access then that other carrier may induce a charge, like roaming. In addition to this aspect of wifi calling because your means of access the AT&T network is via a pure IP network and not something like VoLTE then they cannot determine your physical location and as such complicates the E911 service.

Scenario:

You are up in your cabin in the woods and the Internet service is provided by someone else other than AT&T and you have zero AT&T Wireless coverage up there. Let's say it s fishing trip but the wife stays at home and the two of you decide to use your AT&T Wireless service phones. Your access to the network is 3rd party over IP, hers on the other hand directly and traditionally on AT&T's network. The interconnect should appear as if you are on AT&T network on both ends, but they have zero control of that 3rd part Internet provider. I can imagine some could setup a metering based on protocol-based traffic and charge their customers but I doubt that is happening. Now, on your end it doesn't consume your wireless data, and not in her end either.
