These diagrams are obviously incomplete.
The axes need labelling.
The units should be displayed on the axes.
Arrow heads need to be drawn.

Hovering Vector Diagram

Vr = 192 m s^-1
Vi = 8.42 m s^-1
This is a blade element near the tip of a H300 in the hover.

This is a test diagram for the power on, hovering case.
The induced flow is from above and acts to reduce the angle of attack

Vertical Autorotation Vector Diagram

Inboard Blade Section

Mid Span Section

Outboard section near tip

In this case the airflow is from below, and is termed rate of descent airflow.
The rate of descent airflow is assumed to be constant across the disk and no allowance is made for blockage of the airflow by the fuselage.

Tip Secton

Here Vc adds to vi reducing α
