A relatively low surface temperature means that reg giants radiate relatively little energy per area unit, but since they have a very large surface area, the total amount of energy radiated is enormous.
The other stars do not appear as bright as the sun because they are much farther away. Even the closest stars apart from the sun are hundreds of thousands of times farther away. In terms of actual brightness, some stars are brighter than the sun.
Smaller stars like our own expand into a red giant and then eventually collapse into a white dwarf, the more larger stars like a bright giant star expand into a hyper giant or a super giant. Super giant stars can go supernova and collapse into a neutron star, a white dwarf, or a black hole. The hyper giant stars go hypernova and make a gamma ray that eventually ends into a black hole.

stars come in a variety of colors. red, bright blue, yellow like our sun and even white. stars come in many different sizes too from 10 times the size of our sun to the size of a small island.
Yellow stars are the second hottest, Blue stars are the first hottest. Red stars, even though they are they can be the biggest they are the coldest type of star, they are still hot, but not as hot as compared to other stars.
A star on "main sequence" is a period in a stars evolution.A white dwarf is a stellar remainA supergiant star is the size of a very big star.So they are completely different and not even related.
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
For example, Antares and Betelgeuse. (Even though the Sun is not categorized as a supergiant, don't forget that compared to anything on Earth, and to the whole Earth itself, the Sun is not a small thing.)
The sun is not the only star... There are many many others in the universe, they shine so bright that you can see them in the night sky even though they are very far away...

Its callled light pollution, the sun shines so bright the it obscures even the brightest of stars.

Bright stars are rare, dim stars are common, so class M are the most common that we can see, but even dimmer ones are postulated to be even more common.
Even though the rain hides the stars, even though the mist swirls the hills, even when the dark clouds veil the sky, God is by my side. Even when the sun shall fall in sleep, even when at dawn the sky shall weep, even in the night when storms shall rise, God is by my side. God is by my side. Verse 1 Bright the stars at night that mirror heaven's way to you. Bright the stars in light where dwell the saints in love and truth. Verse 2 Deep the feast of life where saints shall gather in deep peace. Deep in heaven's light where sorrows pass beyond death's sleep. Verse 3 Blest are they who sing the fellowship of saints in light. Blest in heaven's King. All saints adore the Lord, most high.
Yes; its main stars are bright enough to be seen even with normal city lights.
