This solution solves the test cases partially.

Solution:

public class Solution {   

    public static void main(String[] args) {
       
        Regex_Test tester = new Regex_Test();
        tester.checker("(?=^(hh+)\1+(aa+)\2+(?<=a)(cc)+(?=k)(?<=c)k(kk)*`$)(?=.*a{6,})(?=.*(?<=c)k{5,21}(?=$`))"); // Use \\ instead of using \
   
    }
}
