I know it is incomplete, I am going to fill in later
Animated Multiverse
DCAU: Connected to Brave and the Bold and TTGvTT. Has a counterpart in the New 52 Multiverse called Earth-12, but it is in the Batman Beyond era and sometimes makes references to events from Earth-Prime or similar events as it being its past, so it is not the "real" DCAU, is more just the "Universe of Batman Beyond Comics". Also now it has another, closer counterpart after Dark Crisis.
Brand New Metropolis: From an episode of the DCAU.
Justice Lords Universe: From an episode of the DCAU. Has a counterpart in the New 52 Multiverse called Earth 50.
Justice Guild Universe: From an episode of the DCAU.
Earth D: From the DCAU Infinity comics.
Earth X: From the DCAU Infinity comics.
DCAMU: Connected to TTGvsTT.
Earth 23: Batman the Brave and the Bold Earth
Brave and the Bold Evil Universe: Adaptation of Earth 3 from the comics. Connects to Earth 23 in Brave and the Bold.
Teen Titans Universe: According to a tie-in comic Batman from this Universe looks like the Batman from "The Batman", so could be the same universe.
Teen Titans Go Universe: There are theories about it being being the 5th dimension. The majority of this multiverse is made up of TTGvsTT cameos and Batman Brave and the Bold crossover episodes, so if Teen Titans are 5th dimensional beings that can travel multiverses and the Brave and the Bold multiversal guests are summoned by Bat-mite, the whole existence of this multiverse is put into question. In the LEGO Dimensions Teen Titans Go! Level Pack the animated Teen Titans travel with a Raven spell to the LEGO version of its universe that was connected with the LEGO multiverse versions of the Beetlejuice, The Goonies and Ghostbusters universes between others.
DC Super Hero Girls Universe: Has crossed over with Teen Titans Go in multiple occasions but has been shown in the Post-Dark Crisis (or some event like that) comics multiverse as Earth 96. Maybe is a multiversal counterpart.
Tiny Titans Universe:
New Earth like Universe (TTGvsTT): There is an Earth that seems New Earth from the Post-Crisis Multiverse, so, the TTG can either travel between multiverses or this Earth is just an Earth that LOOKS like New Earth but is not.
Crisis on Two Earths Good Universe:
Crisis on Two Earths Evil: Universe: Another adaptation of Earth 3.
Beware the Batman Universe:
The Batman (Animated TV Show) Universe:
Scooby-Doo and Batman Crossovers Universe:
Earth-66 (Or an equivalent): Appears in Brave and the Bold.
Earth-89 (Or an equivalent): Appears in Brave and the Bold.
