Is it possible to terraform a hot planet?

I want to make a hot planet habitable for mankind. It could be a planet in the habitable zone like Venus or outside of the zone like Mercury. These are just examples.

Someone said here: Terraforming a very cold planet? that terraforming a cold planet is easier that a hot one. Still, is it possible to make a planet colder?

Example 1: A planet in the habitable zone is too hot for human habitation due to atmospheric reasons. Can it be cooled down?

Example 2: A planet is too hot due to solar proximity. Can it be cooled down? Can it be moved away from the star?

What are the different techniques or technologies that could be used to lower the surface temperature of a planet?

*including possible not too far future technologies.
