Hotter stars flow with light that is more intense at shorter wave lengths. The hottest stars emit their radiation in short violet light wavelengths. Their light appears blue white when observed.
No, glow in the dark stars are not considered luminous objects. They are phosphorescent, meaning they absorb light and then slowly release it in the form of glowing light. Luminous objects emit their own light, while phosphorescent objects like glow in the dark stars require an external light source to charge their glow.
Stars emit their own light due to nuclear fusion in their cores, making them glow brightly. Planets, on the other hand, do not produce their own light but instead reflect light from a nearby star (usually the Sun), causing them to appear as glowing objects in the sky.

Emission nebulae glow due to the ionization of their gases by energetic radiation from nearby hot stars. These stars release ultraviolet light that strips electrons from atoms in the nebula, causing the atoms to recombine and emit light at specific wavelengths, creating the colorful glow seen in these nebulae.
Stars, galaxies, and quasars are among celestial objects that emit their own light. Stars, such as our Sun, undergo nuclear fusion to produce light and heat. Galaxies contain billions of stars and emit light due to the combined glow of these stars. Quasars are supermassive black holes with surrounding disks of gas that emit powerful radiation.
Stars glow because they are hotter than the surrounding area. See related question.

No, they reflect the light from surrounding stars.
Stars generate light by nuclear fusion. That happens in their cores, but the outer layers glow with it.
When some objects get hot enough, they glow, given off a faint red light . If they get even hotter, the glow turns into white light. The objects are said to be white light
The fusion occurring in the stars cause large amount of light, heat, and radiation causing the stars luminosity.
It all depends on how close stars are to the cloud, and how intense those stars radiate energy. A nebula will glow with a blue colour if it simply reflects starlight (the blue is from the same mechanism our sky is blue, from the scattering of light). This occurs when a nebula is too far from stars, or the stars are too cool to generate enough radiation to ionize the hydrogen. Nebula will glow red if they are close enough to stars to absorb energy - that energy is re-emitted by the nebula as red (from the ionization of the hydrogen, which then glows red).
No. All stars are hot. For stars on the main sequence, the largest it is, the hotter it is. When a star leaves the main sequence to become a giant or supergiant it will cool down, but will remain hot enough to glow brightly.
The sun, light bulbs, fire, stars, and glow sticks emit light.

This is due to light pollution. The glow of the city lights can conceal stars.
