Actually Welcome to the Concept of the Potential Energy.

Here lets calculate it one by one ;-

1.) P = mgh ==> 100*9.81*202===> 198162 Joules

2.) P = mgh ==> 90*9.81*202 ==> 178345.8 Joules

3.) P = mgh ===> 45*9.81*202 ===> 89172.9 Joules

4.) P = mgh ===> 58*9.81*202 ===> 114933.96 Joules

5.) P = mgh ===> 0.001*9.81*202 ===> 1.981 Joules

6.) P = mgh ===> 1.00*9.81*202 ===> 1981.62 Joules

7.) P = mgh ===> 1.998*9.81*202 ==> 3959.27 Joules

8.) P = mgh ===> 1.5*9.81*202 ===> 2971.43 Joules

9.) P = mgh ===> 0.1*9.81*202 ===> 198.162 Joules.

Above we calculated the potential energy for every mass given above.
