Hidden variables are theoretical properties that are not directly observable but are thought to influence the outcomes of quantum mechanical experiments. They are proposed to provide a more deterministic explanation for the randomness observed in quantum mechanics. However, the existence and significance of hidden variables in determining outcomes of quantum experiments is still a topic of debate among physicists.

The quantum mechanical model is the name of the atomic model in which electrons are treated as waves.
The quantum mechanical model is called the quantum theory.

Stephen Hawking worked on quantum gravity throughout his career, but one of his notable contributions was made in the 1970s, when he investigated the quantum effects near black holes and proposed theories to explain the relationship between quantum mechanics and gravity.
It is an attempt to merge quantum mechanics and the General Theory of Relativity.For more details, I suggest you read at least the overview in the Wikipedia, article "Loop quantum gravity".
Not sure what you mean by "derive" quantum theory; that's along the lines of "deriving" gravity. In our Universe, quantum theory is the only one we've developed that matches experimental evidence. In all cases, quantum theory was developed mathematically simply because no other explanation existed that would match what occurs in our Universe. Whether we like it or not, whether we really understand it or not, we are in a Universe that obeys quantum theory.

Yes, the quantum mechanical model of the atom was proposed by Niels Bohr in 1913. He incorporated the principles of quantization into the existing model of the atom to explain the stability of electron orbits and the emission of spectral lines.
