Darth Vader never knew he had twins until that final battle on the second Death Star. The force ghost of Obi Wan had warned Luke to bury his understanding of Leia deep or Vader would be able to sense his feelings..
Correspondingly, did Darth Vader know he had kids?
No. At that point he doesn't even know Luke is his son and that's what starts his interest in finding "Young Skywalker." He shows his surprise at learning that Luke has a sister in Return of the Jedi when he says he sees Luke's feelings are strong for his friends – then adds, in surprise, "Sister."
Secondly, does Darth Vader know he is Anakin Skywalker? Just because Vader knows this hotshot pilot is named Skywalker does not necessarily mean he's Anakin Skywalker's son. Vader DID know the Skywalker he was pursuing was Anakin Skywalker's son and he was trying to keep it hidden to get to Luke before the Emperor found out.
Furthermore, did Darth Vader know Luke was his son?
During the Battle of Yavin, it's fairly clear that Vader does not know that Luke is his son. And he isn't surprised when the Emperor later indicates that Luke is the son of Anakin: PALPATINE: The Force is strong with him. The son of Skywalker must not become a Jedi.
How did Vader find out about Leia?
He likely figured it out who it was at the same time he found out she existed -- by probing Luke's feelings during the duel in Episode VI. If not, there's probably no way he could have known it was Leia. And even if he doesn't, he can talk to Luke as an elderly force ghost and Luke can tell him.
