One very short answer to the question that you ask in the title of your question: "Why is Belarus pro-Russia while Ukraine isn't?" is that Belarus is a faux-democracy with a strongman dictator like Russia, and Ukraine is a new, and real, democracy (with many challenges). The leader of Belarus, Alexander Lukashenko, is very similar to Russia's Vladimir Putin in terms of how he, Lukashenko, runs his country - portraying himself as being an elected leader while actually maintaining undemocratic control of such things as the media in the country and suppressing freedom of expression in order to remain in power regardless of what the people of Belarus really want.
You went on to ask a number of other questions, all of them worthy of longer responses, but let me just offer that Ukraine isn't that different than most of the former Soviet states (Russia and 14 others), many of which are glad they're free from Soviet/Russian occupation (a forced occupation of over 350 million people). Ukraine has pushed for democracy at least since they were the first former Soviet "republic" (they weren't real republics) to transfer governmental power through a peaceful election in 1994. They have struggled with achieving democracy ever since. Ukraine's democratic success appears to be one reason Putin is obsessed with it - having a successful real democracy on Russia's own boarder is a threat to Putin's way of running a country. Placing your questions in a larger context, Putin has also referred to the collapse of the Soviet Union as "the demise of the Soviet Union was the greatest geopolitical catastrophe of the century,”the greatest geopolitical catastrophe of the century," and seems to feel he needs to reverse this, by force, if necessary, regardless of the will of the many millions people he is willing to subjugate in order to achieve this.
