Most of these show take place on their own, unnamed and unnumbered Earths. Of the ones you named, this includes Beware the Batman, Green Lantern: The Animated Series, and Superfriends. Teen Titans Go! is a spin-off of Teen Titans, so they share the same universe, but it is otherwise separate. Of these, only Young Justice has (to my knowledge) a place in the New-52: it's set on Earth-16.
The major exception here is the DC Animated Universe (DCAU), which was a shared continuity that included bunch of animated series and movies (plus some other stuff, of questionably canonicity). This universe is actually it's own isolated multiverse (there's 3-4 Earths on it), and was active from 1992 through 2006. The list of series set in this universe are:
- Batman: The Animated Series (1992-1995)
- New Batman Adventures (1997-1999)
- Batman Beyond (1999-2001)
- Superman: The Animated Series (1996-2000)
- Static Shock (2000-2004)
- Zeta Project (2001-2002)
- Justice League (2001-2004)
- Justice League Unlimited (2004-2006)
As far as animated movies are concerned, they also generally exist in their own isolated universes. Again, the DCAU is an exception, as it included the Batman animated movie series:
- Batman: Mask of the Phantasm
- Batman: Mystery of the Batwoman
- Batman & Mr. Freeze: SubZero
- Batman Beyond: Return of the Joker
(Of note: Superman: Brainiac Attacks looks like a DCAU movie, and came out at around the same time, but it doesn't share continuity).
There is also another large shared animated movie universe, called (not surprisingly) the DC Animated Film Universe, that is still active. It includes a number of existing and upcoming animated movies:
- Justice League: Flashpoint Paradox (*)
- Justice League: War
- Son of Batman
- Justice League: Throne of Atlantis
- Batman vs. Robin
- Batman: Bad Blood
- Justice League vs. Teen Titans
- Justice League Dark (upcoming)
- Teen Titans: The Judas Contract (upcoming)
(*) "Officially", Flashpoint Paradox is not part of the DC AFU -- the concept was invented by WB as a response to the popularity of that movie. However, the post-credits scenee is actually the opening of Justice League: War, strongly implying that Flashpoint Paradox is "unofficially" in the same continuity; since the entire movie takes place in an alternate timeline, there's really no room for discontinuity to occur anyway.
