There are millions of stars that fit that description. On the Main Sequence a star needs a spectrum of type A to be around 9000 degrees, and 1 to 20 times the luminosity of the Sun means an absolute magnitude in the range 1.2 to 4.7. For example Sirius.

..... something wrong with it. Generally luminosity is related to temperature.
Yes.

Don't write "the following" if you don't provide a list - it doesn't make any sense.
Sirius
Its surface temperature and luminosity increase.
..... something wrong with it. Generally luminosity is related to temperature.
as surface temperature increases, luminosity increases
Both the absorption and the luminosity of a blackbody in equilibrium increase in magnitude with increasing temperature, and the spectral distribution of the luminosity increases in frequency (decreases in wavelength).
The bigger the star's radius, the greater its surface area which emits the light. The bigger the temperature, the more luminous is the light the star is emitting.
Yes.

As temperature decreases, luminosity will also decrease As radius increases (and with it surface area, but radius is a much easier to work with if you're trying to compare stars so we usually say radius) luminosity will also increase. If both are happening at the same time, it is possible that the luminosity of the star will remain more or less constant. Often one change will dominate the other, such as when a star goes through the red giant phase when the increase in radius has a far greater effect than the drop in temperature, and the star becomes more luminous.
They compare surface temperature (horizontal axis) and luminosity (vertical axis).
