I'm fairly certain it has been stated by the developers that Twilight is not immortal.

Besides, nothing has stated that Alicorns are immortal. Perhaps they are, perhaps they simply have a very long lifespan. Also, nothing states that Celestia was full grown when she banished Luna.

Age is a rather mysterious subject in the series, anyways. Even the main character's ages are unknown.
