Were these ladies really witches?

Who was Daryl?

And, that ending scene...

• did the ladies embrace - and learn to control - their powers?
• will their kids grow up to be warlocks? or Damien children?
• and what about Daryl, stuck in the TVs...he's apparently still alive, but, where? Doing what?

Maybe I was tired and missed all the dialog in the movie that might have answered these questions.
