In Europe, virtually every country was invaded by Italy, Germany, or the Soviets. Germany invaded Poland, Denmark, Norway, the BENELUX nations, France, Greece, and Yugoslavia. Later they invaded the USSR. The German north African campaign did not technically invaded any 'countries' since Libya was an Italian colony and Egypt a British one. The Russians invaded all the nations on their western border - Poland, Estonia, Latvia, Lithuania, Finland (and Romania - via threats in 1940). Later in the war the Russians invaded Hungary, Bulgaria, Germany, and Slovakia. Italy campaigned in Albania (technically a protectorate prior to the war) and Greece. They also invaded France - barely. The English and Americans invaded Germany after liberating France/Benelux. They also fought a long campaign in Italy, but this was mainly of liberation, since Italy joined the Allies in 1943. In Asia, the Japanese didn't invaded any independent countries during WWII. The Chinese war was well under way before WWII. Thailand was allied to Japan. All other Japanese conquests were of colonies and possessions of the various European and American powers.
Quite a few. Almost all of Europe, including Japan and China, all of the USA and Australia, and Northern Africa.
