No, they aren't immortal. The only known immortal inhabitants of the Tower are Zahard and the 10 Family Heads.

The effects of aging can be slowed or stopped due to shinsoo, not to mention time runs a little differently in the Tower and, as such, so too would aging.
 * Sometimes when people start to handle Shinsoo, their growth stops before they become adults.

Just to add, the average time it takes to climb the Tower is 500 years; Urek Mazino did it in the fraction of that time. Both Quant and Lero-Ro are over 600 years old but they still look relatively young :) Basically put, shinsoo is the reason Rankers live longer and look younger ^^
