Try this:

SELECT STUDENT_ID, Numbers, IF(@marks=(@marks:=Numbers), @auto, @auto:=@auto+1) rank 
FROM (SELECT STUDENT_ID, Branch_id, Class_id, SUM(Numbers) Numbers
      FROM quiz_user 
      GROUP BY STUDENT_ID 
      ORDER BY Numbers DESC, STUDENT_ID 
     ) AS A, (SELECT @auto:=0, @marks:=0) AS B
WHERE Branch_id = 5 AND Class_id = 1;
