In our Solar System only Earth. Venus and Mercury are too hot and the outer planets too cold for liquid water.
The sun is not called the Goldilocks planet. The term "Goldilocks planet" refers to a planet that is neither too hot nor too cold, and is capable of supporting liquid water on its surface, like Earth. The sun is actually a star, not a planet, and it is too hot to support life on its own.
Earth is the only planet that is the right temperature to support liquid water on its surface. All the others are either too hot or too cold.
Unfit for life : too hot, too dry (no liquid water), no oxygen. and the day was just 8 hours long.
It is too cold for liquid water to exist on the surface
Mars is a planet that is too cold for liquid water to exist on its surface. Almost the entire surface of Mars is covered in ice.

No. Venus is too hot for liquid water to exist.
The Earth is the only planet to have water in a liquid state because it is neither too close nor too far away from the sun. If it was too close, the sun's heat would vaporize the water . If it was too far away, the water would be frozen solid.
It is too cold for liquid water to exist on the surface
Eris is too cold for liquid water, though it does have a significant amount of ice.
Conditions on Mercury are far too harsh for the kinds of life we are familiar with. It is far too hot in the day, too cold at night, has no liquid surface water, and almost entirely lacks an atmosphere.
