Is it bad to do the helium challenge?
A little helium isn't harmful, but inhaling an entire balloon-full can block oxygen to your brain, which might cause you to pass out. There has been at least one death from breathing helium from a pressurized tank instead of a balloon, too.

Was Mars 3 a manned spacecraft?

Will a balloon pop in space?
That depends on how much air is in the balloon and how high the temperature gets. As the sun shines, it heats the air in the balloon. This causes the air to expand. This air pushes against the insides of the ballon making it swell up and stretch. If there is enough air in the balloon and the temperature increases to a high enough level, then the air pressure can get to high, it will cause the balloons skin to stretch to far and the balloon can pop.
Kinds of air filled in the balloon?
no, when we blow a balloon we actually fill carbon dioxide from aor lungs into it,...so the proportion is not same,there is more carbon dioxide in the balloon as compared to its surroundings as the normal air contains approx 0.4% of carbon dioxide and different percentages of other gasses.
What is the gas in a balloon?
If it has been blown up by a machine it is likely to be helium. If you blow it up by mouth, it is just air, which is a mixture of a number of gases, particularly oxygen, carbon dioxide, and nitrogen.
