How to pay yearly for iCloud with 200 GB of Storage how much? Where can see it? How to set it?

Our questions:

1.      After I log in my account from https://appleid.apple.com,

where can see this bill or my receipt?

2.      Is there the yearly plan / charge for iCloud+ with 200 GB of Storage, how much? Where

can see it? Set it?

3.      My wife has Apple account too, can we use Apple’s family sharing services/plan for

our Mac Book Air, iPad, iphones? If yes how to do?

Looking forward to having your

response, thanks!
