• White dwarf stars are for lower - mass stars.
• The most massive stars end as black holes.

For question 3:

• The brightness of a star as seen from Earth (apparent brightness) is related to its actual brightness (which can be related to size and temperature) and its distance from Earth.
• Star 1 has a relatively high temperature (similar to the Sun's surface temperature range), is slightly larger than the Sun, and is the closest to Earth (4 light - years) among the four stars.
