We can never know.
Because as the distance increases the visibility reduces, so hypothetically there can be some stars which are so far away that there light never reaches us and we will not know about their existance.
If you question was about just the farthest star which is visible, it cannot be greater than the diameter of the "universe"

Hi. I assume you mean a visible star. The most remote stars detectable from earth are supernovae. I saw one in a 6" telescope that was many millions of light years away (in M81), but the Keck telescope and others can see very much farther. On the order of several billion light years.

Hard to say. As our telescopes become more sensitive, we discover ever more distant objects. The current estimate of the age of the universe is approximately 13.7 billion years. Therefore, the most distant objects could be expected to show up 13.7 billion light-years away. That's about 83,000,000,000,000,000,000,000 miles.
(I have no idea where Green Meklar gets the 300 billion figure.)

Probably about 300000000000 (three hundred billion) light years away (that's the approximate diameter of the Universe).

It is so far away that it's light has yet to reach us so we cannot even see it yet.

too far to say
