What about Twilight and Cadence? They are princesses which equate to goddesses in this world. Do princesses have immortality?
I would say no. Looking at Luna and Celestia, it's understood they were born/created as alicorns and have demonstated agelessness since the first episode. Cadance was born as a pegasus but was later on turned into an alicorn by Celestia. As we can see from flashbacks of Cadance, she appears to have aged normally. Twilight underwent the same transformation as Cadance so I figure she isn't immortal in any way.
Also, former mlp:fim writer Meghan McCarthy has gone on record saying that Twi won't outlive her friends for being an alicorn. If we did fastforward several hundred years into the future, I'm sure it would just be the two sisters unless they decided to create more "incomplete" alicorns.
Then again, there's always magically prolonging one's life which opens a whole nother can of worms...
