Britain, France, Russia & the US are common to the Allies in both WW1 & WW2. They are opposed by Germany in both wars. In WW1 Italy & Japan were both on the side of the Allies, in WW2 they were on Germanys' side. Turkey was on the side of Germany in WW1 & Neutral in WW2. Austria/Hungary was on the side of Germany in WW1 & were also on Germanys' side in WW2, (although it might be said by force rather than choice.) although they were then 2 separate countries.
Russia France, the US and Canada were the major fighters on Britain's side in WW1 if you would like to find out who else fought you can always Google it

Zimmerman note: said that Germany would promise a few states to Mexico if they join the war on there side
