I'm learning Esperanto using Duolingo and am a total beginner, so sorry if the questions sound silly. (Mi estas komencanto!) I have a bit of a doubt in the following two points:
Are Kiel vi fartas? and Kiel fartas vi? both correct? If not, which is, and why?
Are the following sentences equivalent? Nedankinde, kara! , Vi estas bonvena, kara! and Bonvenon, kara! P.S.: Is it wrong to say, Vi estas bonvenon, kara!
Dankon!
Kiel vi fartas? is how you'll usually hear it, but the other word order is OK and means the same thing.
Nedankinde is a polite thing to say when someone thanks you.
Vi estas bonvena is a way to tell someone that they are welcome somewhere. (You are welcome in my house - vi estas bonvena ĉe mi.)
Bonvenon is a way to welcome someone. (Welcome to our house - Bonvenon ĉe ni)
Finally, your last sentence is wrong. You don't use -n with estas.
