Question

yes. this is a free body diagram because it shows all the subsystems in the collision.
yes. this is a free body diagram because it shows all the forces acting within the system.
no. this is not a free body diagram because it is missing the vector force pointing up from the steering wheel.
no. this is not a free body diagram because it shows two or more interacting subsystems of the collision.

Explanation:

A free - body diagram shows all external forces acting on a single object. The given diagram shows a person in a car with forces indicated. It is not a free - body diagram as free - body diagrams focus on a single body and its external forces, and this shows multiple interacting subsystems (person and car parts).

Answer:

No. This is not a free body diagram because it shows two or more interacting subsystems of the collision.
