As far as I know, DC has several different, non-connective, live action universes.

1. Gotham

2 Arrow, The Flash, Vixen (animated), and Legends of Tommorow (coming in 2016)

3. The DC Cinematic Universe: Man of Steel, Batman v. Superman, Suicide Squad

4. Supergirl

5. Constatine, I don't know if Lucifer will be connected to it.
