[Star Wars] What kind of Jedi was luke by the end of episode IV? Could he easily take on a Jedi master? What was his stance on the force?

By the end of IV, Luke's not at all a Jedi.  He's barely realizing his connection to the Force.

By the end of VI, he's learned enough and resisted temptation enough to call himself a Jedi Knight (he does).  Still though, he was only able to beat Vader by giving into rage momentarily, and was utterly at Palpatine's mercy until Vader saved him.  Definitely a Knight, definitely far short of a Master.  Standing firmly on the Light Side, though perhaps not as unwaveringly as Obi-Wan or Yoda.

Still though, Legends has him as the most powerful Force user ever, greater than his father, Yoda, or Palpatine.  If that's kept in the film continuity, then it's possible that Luke in VII will be a wise and incredibly powerful Jedi Master.
