A composite number is a positive integer that has at least one positive divisor other than one and itself. In simpler terms, it is a number that can be divided exactly by numbers other than 1 and itself.

Let's analyze the given numbers:

- **2**: Prime (only divisible by 1 and 2)
- **11**: Prime (only divisible by 1 and 11)
- **9**: Composite (it has divisors of 1, 3, and 9)

Therefore, among the numbers 5, 2, 11, or 9, the composite number is **9**.
