No, the only dungeon we have at the moment is the Slider's Labyrinth (Bronze Dungeon). The others will be implemented on future update, though.
There is no seed for the Silver Dungeon, as Dungeons do not require seeds, and the Silver Dungeon hasn't been released yet
Noone knows but the Lore. (who is problebly based on Liberty)
also will the original mod be rereleased?
By original, you mean the Aether 1? No.
The Aether 2 is supposed to be an update to the Aether 1 series, so they won't bring it back... But all of the cool features of the Aether 1, such as the Gold and Silver dungeons should be brought back to the mod very soon.
