Yes. You are right.

Yes, for instance, the nearest star after the sun is about 4 light years away. We are actually seeing a four year old image of that star from earth.

No one really knows. It has been supposed that we are seeing images millions of years old. But scientist really don't understand light enough to make that assumption. A light year is an assumed 'distance', not a measure of time. Light has not always been constant. It may well travel much, much faster than originally thought. If Einstein was even close, then time may not be relative. And it is already over my head. The bottom line is-don't get too worked up over "long ago". There is just too much myth in 'millions of years'. We don't know. It is just a guess-at best.

Yes because it takes a lot to the light to come on the Earth.
One similar information:
If sun would shut down now we would realise that in 8 minutes. It depends on how much is the distance between Earth and star.

Actually yes...in fact many of the stars you see no longer exist, but the light sent off years ago is still reaching earth.

Yes, we see what most stars were 1000 or more years ago.

The closest star to us is called Alpha Centauri...it is aproximately four and one quarter light years away.....I.E. it would take 4.25 years traveling at 186000 miles per second to get there.....the light you see is 4.25 years old. This is one of 200 billion stars in our milkyway galaxy. There are billions and billions of other galaxies!

Yes they are. In fact when we see Quasars, we are seeing them as they were some 10 billion years ago. They are very very distant and very young in respect to the big bang.

Oh yes. A star that we now might not be there at all now!

Yes, even our own sun, you see it as it was 8 minutes ago.
This is what's odd, if you look at the sun, and it exploded, you'd feel the shockwave, and evaporate BEFORE you saw the sun explode if this theory is true.
