Kind of a quick, silly answer, if you don't mind.

Can we compress any object to create black Holes?

The pressure at the bottom of the ocean is enormous, it would kill a person in a fraction of a second, but it's tiny compared to the pressure in the center of the earth, and that's tiny compared to the pressure in the center of Jupiter, and that's tiny compared to the pressure inside the sun, and the pressure inside of the sun is also, tiny-tiny-tiny compared to the pressure required to create a black hole.

In the science videos and discussions, they say that, we can create Black hole from any object, i mean for example, if we are able to compress EARTH to the size of the Tennis Ball, then we can create Black Hole, Is it True?

I think it's closer to the size of a golf-ball, but yes, that's true. But it's also impossible. There's no known way to do that. We probably don't even have the means to crush a single car to the size of a golf-ball or tennis-ball and if we did, it would just rebound once we removed the compression force. Matter is enormously difficult to crush anywhere close to that much. That's why it only happens in the core of large stars. That's the only place where there's enough pressure.

does Nuclear Reaction is only to fight gravity, it does not play any other role in creating Black Hole.

Nuclear reaction doesn't play a role in creating a black hole. A black hole by definition, is gravity strong enough that the escape velocity is greater than the speed of light. Nuclear energy doesn't come close to that. Nuclear fusion prevents black holes form forming when there's enough matter for a black hole to form, but that's about it. Black holes can't happen without an enormous amount of mass, about 3 solar masses and no sustained nuclear fusion.
