The following are some benchmark light times:
Sun - ~8 minutes
Pluto - ~249 minutes (about 4 hours 9 minutes)
Oort Cloud - 1 light year
Proxima Centauri (closest star) - 4.2 light years
Pleiades (Seven Sisters) - 440 light years
Orion Nebula - 1.5 thousand (1,500) light years
Ring Nebula - 2 thousand (2,000) light years
Eta Carinae - 8,000 light years
Milky Way Centre - 25,000 light years
LMC - 160,000 light years
Andromeda - 2,500,000 light years
Whirlpool Galaxy - 37,000,000 light years
The Mice - 300 million light years
The Hubble Deep Field - 13 billion light years
Edge of Universe - At least 13.4 billion light years
In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.
The stars from the Big Dipper are approximately 80 light years away from Earth, meaning it takes 80 years for the light from those stars to reach us. This means that the light we see today from the Big Dipper actually left those stars 80 years ago.
The stars we see are so far away, that their light can take hundreds or thousands of years to reach us. So long after the light we saw left the star, but before the light arrived here, the star may have blown up. We would not know for a long time after that. So many of the stars that we do see may be long dead.
The light from our Sun will take about 2.5 million years to reach the Andromeda Galaxy.
When traveling at the speed of light, about 8 minutes. When walking, alot longer.

Light travels at about 300,000 metres per second. The time taken for that light to reach us would depend on the stars distance.

Not for the stars you can see without a telescope. All of the stars you see at night are within a few hundred light years of Earth, so it does not take the light more than a few hundred years to reach us. There are stars in other galaxies that are millions or even billions of light years away. That light does take millions to billions of years to reach us, though the stars are too far away for us to thee them individually.
It will take no time at all
It takes about 8 minutes and 20 seconds for light from the sun to reach the Earth.
0.28 Seconds
About 8 minutes
Light years.
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
2 million days
approximately 3 seconds.
