Life as I know it needs an abundance of Oxygen, Carbon, Hydrogen and Nitrogen, as well as a sweet spot, which refers to the planet being just close enough, but not too far away from the star it orbits. Our planet happens to be made up mostly of the above elements plus Silicone and a few others, but noone has ever been able to prove that the combination of other elements can or cannot support life. Hopefully, we find that out soon :)
Never. Nibiru does not exist.
The sun is essential to life on this planet, so if the sun was not producing light/heat - life on this planet would no longer exist.
Yes, this is possible. Some would argue that whether or not we find such life, it is nearly impossible that it does not exist somewhere.
Mercury is the smallest planet in the solar system. It's possible (if unlikely) that another planet could exist out beyond Neptune, but if so, it would almost have to be larger than Mercury to meet the 'clearing its orbit" requirement (failing this test is why Pluto is no longer considered a planet).
The planet Saturn could theoretically float on giant planet like Jupiter because Saturn has a lower density than Jupiter due to its composition being mostly gas and liquid. This would mean that Saturn would have the ability to "float" in the atmosphere of Jupiter, similar to how a boat floats on water.
Would life exist on what planet? Earth? Mars? Yes, even if not human, trees and plant vegitation

It isn't a planet. It doesn't exist in the solar system anymore. As a dwarf planet, but not as a proper planet.
Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
Surfactant molecules allow many things to exist. This would include alveoli in the lungs, and particles of colloidal dimensions, such as micelle.
Never. Nibiru does not exist.
Yes. There is no condition that would exist to prevent it.
It wouldn't exist. This planet itself is made up of chemicals, which make the compounds etc. from which the planet and everything on it are formed.
No. There also would be very little chance life would exist on the planet.
If a planet was composed of a fuel and an oxidizer, it could be set on fire. It is unlikely that such a planet would exist for long.
living things would not exist as earth is the only known planet which has life.
Frozen to death.
