Is it “ more friendly” or “friendlier” of comparative form Also, plz tell me the superlative form of the word "friend", thanks a lot.

what does "possessive "and object pronoun"mean ? for example, I don't mind doing sth. what does possessive mean here.

Can I say it in this way？“Do you mind my sitting here?" or I should say" Do you mind me sitting here?" Is it "Do you mind if I sit here ?" the most popular way to say so? Can I also say it in this way "If you don't mind, can I sit here?" Thank you.

Which one is correct? Is it " don't want to do sth" or " want not to do sth" Hey, I'm learning the negative form of "to do sth." It is said the negative form of " to do sth" is "not to do sth." So should I say " I want not to do sth" It seems so weird to say that way. I'm so confused, please help me out. thx.
