People who are "real" and not afraid to be themselves can be described as

Authentic.

Explanation:

An authentic person is a true person. A genuine person. Someone real, not fake and not trying to be a copy of another, because they are not afraid of being themselves. A person who introduces himself as he really is without pretending to be something that is not just to please others. You recognize that you are unique in the world, confident in your skills and opinions and at the same time aware of your own limitations.
