Sithis, Lorkhan and Akatosh are not related. Well, Lorkhan and Akatosh are but Sithis and Akatosh are not twins. Padomey and Anu are twins, but they are in a state that may or may not be called "dead" since Sithis/Padomey and Anu are NOT divines, they are another entity which is literally energy. They are the creators of the Aedra and the Daedra. Sithis may still be around though since he made business with the Night Mother but Anu is nowhere to be found, the only remnants of it's existence is the Aedra which are half of it's blood.

Also, Padomey did not make Mundus. He created pretty much everything else though.
