How did Tony Stark and Spider-Man survive on titan?
Tony Stark and Spider-Man both are normal human beings, so how can they survive on Titan without any oxygen and also with their power suits broken completely.

Notice the blue skies and white clouds, the green plants, and the water. Since water consists of oxygen, and, since green plants contain chlorophyll (which contains oxygen), then, it's safe to assume Titan had extremely similar, if not the same, kind of atmosphere as Earth.
Other evidence that Titan is environmentally/atmospherically similar to Earth:
A theory could be that Tony & Peter take off their helmets once their suit AI detects(off-screen) that Titan has oxygen to breath. If there was no oxygen to breath they would continue using their helmets/masks.
Remember that when they crash land on Titan, both are wearing full suits with helmet/mask
