It was stated that alicorns retain their youthfullness, but are not immortal. Not even Celestia and Luna. The two of them, however, sice they're so powerful, possess longevity. I believe the writers said that 50 years for everyone is equal to one year for them. So during Celestia's 1000 year reign, that was only like 20 years of her life.

As for Twilight and Cadance, it's uncertain to what their lifespan is. The writers did say that Twilight won't outlive her friends, however, now that she possess both Celestia and Luna's power, she'll likely have an even longer lifespan than what the two of them had. However, it seems that Twilight is grooming Luster Dawn to be her replacement. So once Luster is ready and Twilight gives her her power, then it can be assumed that Twlight will revert to a normal lifespan. It's really the only way she won't outlive her friends.
