No it is not breathable, because the planet is full of dangerous gases such as methane.
You could not build a fire in the normal way on the planet Uranus since there is no oxygen in the atmosphere of that planet. However, if you were on Uranus, in your sealed spaceship with its own breathable atmosphere, and you wanted to build a fire there (which would probably be a terrible idea since it would use up your oxygen supply) that would be possible.
Mercury does not have a breathable atmosphere. There is no planet in our solar system that offers an atmosphere that humans can breathe.

Yes, all planets have atmosphere but to my knowledge mars' is not breathable.
No. There is no breathable air.No. People would not be able to live breathing Uranus' atmosphere, which is thin and consists mostly of hydrogen (which isn't bad for us), helium, ammonia, and methane (all three of which are not at all good for Earthlings in such high concentration).
No, Uranus' atmosphere is over 97 percent hydrogen and helium with clouds of ammonia, methane and other hydrocarbons that give it a light blue hue. So there is not enough free oxygen to breath. Furthermore it has the coldest atmosphere of any planet, reaching down to -224 C, which would be fatally cold.
Inside our solar system, only planet Earth has an atmosphere breathable to humans.
No, it's a planet.
No. The only planet or moon to have a breathable atmosphere is Earth.
No. Earth is the only known planet with a breathable atmosphere. Saturn's atmosphere consists mostly of hydrogen and helium.
