The total weight of five people is: (110+12+113+165438+65438+65438.

The weight of the person in the middle is: 289-11kloc-0/21= 58kg.

Lightest weight: 1 12-58 = 54kg.

The second lightest is: 1 10-54 = 56kg.

The heaviest is: 120-58 = 62kg.

The second weight is: 12 1-62=59 kg.

Five weights: 54 kg, 56 kg, 58 kg, 59 kg, 62 kg.

Analysis:

Weight 10 times, each person weighs 4 times, so the total weight of five people is: 289 kg.

The sum of the weights of the lightest two people is 1 10, and the sum of the weights of the heaviest two people is 12 1, so the intermediate weight is: 289-112/kloc.

Then the sum of the lightest weight and the medium weight is the weight of the second weighing, that is, 1 12, and the lightest weight is 1 12-58=54 kg.

The sum of the two lightest people's weights is 1 10, so the second lightest one is 1 10-54 = 56kg.

The sum of the heaviest and medium weights is the second weighing weight, that is, 120, so the heaviest weight is 120-58 = 62kg.

The sum of the two heaviest people is 12 1, so the second person is 12 1-62=59 kg.
