Yes, Thanos can survive without oxygen because he possesses the physiology of an Eternal, granting him self-sustenance and the ability to thrive in the vacuum of space, much like other cosmic beings, though his home world Titan had an Earth-like atmosphere. While he can breathe oxygen like humans on Titan, his inherent biology means he doesn't need it for survival, and his powers can supplement his energy needs.

But eventually, the lack of oxygen will take its toll. One by one, your major organs will shut down. After only a handful of minutes you will suffer complete organ failure, otherwise known in the medical community as death.
The lowest tolerable pressure of air is about 0.47 atm (475 millibars of atmospheric pressure) - recorded at 5950m altitude. At about 0.35 atm (less than 356 millibars at around 8000m) life is impossible. Pulmonary and cerebral edema lead to death.

The Mark 42 (or XLII) Iron Man armor is special because it's an autonomous, modular suit that can assemble itself around Tony Stark, controlled by microchips in his arms, allowing remote operation and deployment in separate pieces, making it his first "summonable" armor but also prone to malfunctions as a prototype.

On Earth, the limit is around 18–19 km (11–12 mi; 59,000–62,000 ft) above sea level, above which atmospheric air pressure drops below 0.0618 atm (6.26 kPa; 47.0 mmHg; 0.908 psi). The U.S. Standard Atmosphere model sets the Armstrong limit at an altitude of 63,000 ft (19,202 m).
Air / gasses in the body would compress significantly, if not allowed to exit the body. Your lungs would collapse in an instant, and your chest cavity would collapse on itself, until all air has escaped, and then replaced by water. Your ear eardrums would also rapture in an instant.
In hospital settings, 100% oxygen may be delivered -- but even then only on a short-term basis, says Boyer -- less than 24 hours and preferably less than 12 hours. To breathe pure oxygen at that level for any longer can have toxic results, including "shock lung," or adult respiratory distress syndrome.
