Is it possible to travel to exo-planets with a near light speed spacecraft, considering the fact that they hundreds or even thousands of l?
light years away?

There is nothing in physics to suggest that it is possible to travel to anything outside our solar system in less than tens of thousands of years. Even then, whatever reaches it's destination will have been long since frozen over due to energy depletion in the extreme cold (minus 400 degrees F) of deep space.
Fortunately, it appears that those exoplanets you mention are nothing more than boring hunks of rock and ice or huge amorphous gas giants, of which we have plenty to study in our own solar system. Hence travel to other planetary systems is unnecessary, and we aren't missing out on anything of significance by staying here.

in principle, yes you could, provided you built a large enough rocket with enough propellant to reach near light speeds. but in a practical sense, probably not. you would need humongous quantities energy to reach those speeds.
actually, though, you could travel light years distance with even a simple chemical rocket, provided you don't mind a more leisurely pace and are willing to wait millions of years to reach your destination.

No, because the mass of the space craft approached infinity the close to the speed of light IN A VACUUM the speed of the spacecraft gets.

It may be possible with more advance Propulsion and a Generation Craft
We do owe it to ourselves

For starters we don't have a spaceship that can travel at anything close to light speed.

At the moment, we can't. Or, at least, we could *start* the journey, but anyone on the craft now would be long dead by the time it arrived... As a reminder, the twin Voyager craft have been in space for nearly 43 years - and haven't even traveled a single light day out as yet.... We're a long way from traveling light years within a lifetime.

but there are quite a few less than 20 LY away.

not currently, no, but MAYBE tomorrow ???

No it’s not possible
