difference between a Featured, Supporting, and Co-Sta

Question: What's the hierarchy / difference between a Featured, Supporting, and Co-Starring role in an acting resume!?

I'm updating my acting resume and I'm not sure how to label my Film roles!.!.!.one just has a few lines, but the other is a leading role with lots of lines (but not the lead---so what would that be!?)!. also, how do I label the role!? With the name of the character or the kind of part it is (like co-starring, etc!.)!?Www@QuestionHome@Com
