Is it possible that someone could have survived in the Titanicand died later at the bottom of the ocean?

Also - is it possible that there are still trapped air pockets in the wreckage?

No. The wreck of Titanic is about 3800m below the sea level, which means that the pressure is about 380 times the atmospheric pressure. (At that pressure, air shrinks to about 0.26% of the sea level volume.) Even if it there were big enough pockets of air to breathe, and a possibility to keep warm, people would die of nitrogen or oxygen poisoning.
