What were Hitler 's plans with russia if germany won the war?
From the Nazis’ point of view, the war against Russia is a racial war against Jewish and Slavic “races” to build Europe as a racial entity. They planned to destroy Russia permanently, colonize western parts of the Soviet Union, and expel the inhabitants beyond the Ural mountains or exterminate them. 
Hitler planned to divide the new eastern territories into four Reichskommissariats to destroy the Soviet Union as a geographical entity, including:

- Reichskommissariat Kaukasus (RKK): southern Russia and the Caucasus area, except the western part of Georgia and the whole Armenia.
- Reichskommissariat Moskowien (RKM): most of European Russia between the Ural mountains and its boundaries with Finland.
- Reichskommissariat Ukraine (RKU): formerly Soviet Ukraine and Rostov, except the District of Galicia, Odesa, Vinnytsia, and the Crimea.
- Reichskommissariat Ostland (RKO): formerly Soviet-annexed Estonia, Latvia, Lithuania, except Memel, and Soviet Belarus.

The leaders of these provinces, the Reichskommissars, would be direct subordinates of Hitler, and answerable only to him. During Operation Typhoon in 1941, Hitler especially planned to level Moscow, killing its 4 million inhabitants and permanently submerging it under an artificial lake to destroy it as a potential center of Bolshevist resistance.
Where did you get those facts? Can you cite your sources?
Sure, here are several books that outline Germany's violent plans for Eastern Europe during and after the Second World War:

 *Eradicating Differences: The Treatment of Minorities in Nazi-Dominated Europe*, edited by Anton Weiss Wendt
This compilation of essays describes the development of Nazi racial policies and how they were inflicted on civilians, first domestically and then in conquered lands.

*Ostkreig: Hitler's War of Extermination in the East* by Stephen G. Fritz
This book documents *Generalplan Ost*, the overall German strategy of ethnic cleansing and conquest for Eastern Europe, including administrative plans for dividing up the land into *Reichskommissariats*. 

*Bloodlands* by Timothy Snyder
This book details the specifics of civilian atrocities by the German army during the war in the implementation of *Generalplan Ost*, including the attacks on Moscow and Leningrad.

These books document National Socialist Germany's racial fanaticism and its consequences for the civilians of Central and Eastern Europe. The grand plan for German living space entailed killing millions of non-combatants, even after the defeat of the Soviet Union.
