- Would the majority population of DPR and LPR like to break away from the Ukraine?

No, they would not. They voted in very large majorities to be part of an independent Ukraine. Of course, now they are ruled by Russia-linked gangsters, so it is impossible to know what their citizens would like. Common sense suggests that they would rather be part of Ukraine, somewhat democratic, and relatively rich, instead of part of Russia, ruled by a warmongering dictator, and relatively poor.
