Does anybody has got maps with Luftgau boundaries and their changes during course of war?
Your question implies that you are looking for a series of maps - perhaps new ones issued every 6 months or so - running from 1935 to 1945. The only source for a series of maps like that is in obscure British Air Ministry publications and documents found at the British National Archives in London.
However, this work will give you all of the changes in Luftgau boundaries over the course of the war in narrative form - no maps, just detailed written description:
