I dont remember what these words mean!

Hi, am moroccan but unfortunately I’ve forgotten a lot of words. My question is;

what does finna and fniwna mean?
What does ouali (my last name) mean? Does it even have a meaning?

“finna” mean beautiful, “fniwna” same meaning but just make it small but more femenin
“Ouaili” it’s term spell when it’s gone something not good happend or something in trouble sayed
