Answer 1

According to the video, Hertzsprung and Russell set up their data chart for star evolution based on Brightness (luminosity) and Temperature.

For Question 2, without the diagram mentioned, I can't provide a specific answer. However, typically in the Hertzsprung-Russell diagram, most stars are classified as main sequence stars. If you refer to the specific diagram, it might provide a clearer classification depending on what is illustrated.
