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.
Yes, all planets have atmosphere but to my knowledge mars' is not breathable.
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.
No, it's a planet.
Uranus has the coldest atmosphere of all the planets in our solar system. Temperatures in its upper atmosphere can drop to -224 degrees Celsius (-371 degrees Fahrenheit).

Inside our solar system, only planet Earth has an atmosphere breathable to humans.
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.
Uranus has an atmosphere that contains methane clouds. Methane in Uranus' atmosphere absorbs red light, giving the planet its distinctive blue-green color.
No. There is no oxygen in Neptune's atmosphere
