Akatosh would be Bormah, as the dragons refer to him as father.

Arkay would be either Dinok or Kiindah, since he is the god of birth and death.

Alduin is technically a deity so I will include him, his name as a whole doesn't mean anything but when you separate it, it mean Destroyer Devour Master.

Dibella could go by three different names, Brii, Lokaal, or Pruvos.

Hermeaus Mora would be Mindah, as he is the deadric prince of knowledge.

Julianos would be Gahziin, as he is the god of logic.

Kyne is called Kaan on multiple occasions, throughout wordwalls, her shout, as well as scrolls.

Talos would be Kein, as he is the god of war.

I am well aware that most of the names are just translation for their domain but dragons are a fan of keeping things simple.
