@mian you's, of course, is just the possessive singular form of you. For example "Can I borrow you's phone for a minute".
On the other hand yous is the plural non-possessive form such as "Wow I see a lot of people turned up, yous people are awesome"
Finally yous' is the possessive plural form of you, as in "I want everyone to take out yous' phone and hold it up"
@freemo You're = "you are" your = belongs to you
