You friends have answered correctly, However I would like to add more points for some question.
1. Earthworms are known as friends of farmer because
Earthworm moves through the soil that loosens and aerates the soil. This also helps the water to reach the roots quickly.
Earthworm 's excreta increases the fertility of the soil.
After their death, they get decomposed and add humus to the soil.
3. Kabadiwala is a friend of the environment because they collect waste material from us and sell them to factories for recycling. This prevents accumulation of hazardous wastes in the environment.
For rest of the answer, refer to your friends.
