Plz help me !!!!!

go on the profile and click the big green button. Unless you're on mobile, idk.

click on your name at the top of the page, then click on the number next to theperson icon, its next to the envelope. that should have all your friend invites and then you just click accept for people who want to be your friend and sent you an invite.

If you want to add friends click on their name and then next to their picture is a big green button that says add as friend, which will send them an invite. People normally prefer a message as to why you are asking them, then its up to them to accept.
