To answer the question regarding the substances that play a key role in hunger, eating, and satiety, let’s analyze each option:

1. **Testosterone**: Primarily known as a male sex hormone, it is not directly involved in regulating hunger or satiety.
2. **Insulin**: This hormone is crucial for glucose metabolism and helps to signal satiety after eating by promoting glucose uptake and storage.
3. **Leptin**: A hormone produced by adipose (fat) tissue, it plays a significant role in regulating energy balance by inhibiting hunger, which in turn helps to regulate body weight.
4. **Glucose**: While glucose levels can influence hunger sensations (as low levels may stimulate appetite), it's not a hormone itself but rather a molecule that can affect satiety indirectly.
5. **Cortisol**: Known as the stress hormone, cortisol can influence eating behaviors and appetite, especially during stress but is not a primary regulator of satiety.

### Final Answer
The three substances that play a key role in hunger, eating, and satiety are **insulin**, **leptin**, and **cortisol**.
