Yes, stars are luminous.
Stars emit energy in the form of light. The immense temperature and pressure inside stars fuses atoms together in a process called nuclear fusion. This releases energy, largely in the form of light and heat. Some stars shine more brightly than others and this brightness is known as the star's magnitude. There are two types of magnitude.
1. Apparent magnitude - This is a measure of how bright the Star appears to us (this does not take into account how far away from us the star is).
2. Absolute magnitude - A measure of how bright the star actually is once we allow for distance (if it is further away it will appear to be less bright to us but this scale compensates for this).

How can a cool star be more luminous than a hot star?
Luminosity is related to temperature and distance.A cool and thus less luminous star would be brighter than a more luminous star at a greater distance.Our Sun is a relatively cool star in comparison to say Rigel, but because it is closer it appears more luminous and brighter.
