Family member currently in the hospital with multiple organ failure, on a ventilator as a result of internal bleed. in his 30s are there any chance he can survive?! he is in icu?

This is a question best answered by the team managing the case. Some do, some don't. Only those with a full understanding of all the present findings of the case can form a reasoned answer.

More info will be needed for a prognosis. On life support, prognosis is always guarded. On his favor, his age, not always a surviving trait. Hope for the best, prepare for all possible outcomes, your best reference remains the ICU attending, who can place things in proper clinical context.
