If the world wars could be avoided, I could see the following happening.
Britain keeping her colonies, mainly because they were already transitioning the Empire into the Commonwealth, with several Dominions and a few self-governing colonies already. Without WW1, Irish Home Rule would have been sorted. The Indian Question (Dominion status) would be the trickiest step, but could be managed as either a federation similar to Australia and Canada or as separate Dominions based on the Presidencies and the Princely States.
France would probably continue with it's policy of eventual integration with the metropolitan.
The Russian Empire could lose territory if the revolution turns out to be anywhere as messy as OTL, and they WILL have a revolution, just a matter of when. the pressure was building even without the added stress of war with Germany.
Germany also has a good chance of retaining it's colonies if war is avoided.
Belgium losing the Congo, Burundi and Rwanda to a massive uprising, triggered by their oppressive policies.
Spain and Portugal to gradually lose control of their remnants due economic decline.
Italy to integrate Libya into it's metropolitan as per France & Algeria.
The USA to eventually let the Phillipines go, but keeping her other colonies, sorry territories, in the Pacific and the Carribean. In fact, without WW2, statehood for Alaska and Hawaii may be delayed for decades.
Japan to keep Korea and to seize Manchuria as per OTL, although conflict with China and internal resistance to Japanese rule to flare up over time.
The Ottoman Empire still disintegrating, with the resulting chaos in the Near East tempting intervention by Anglo-French forces.
