I believe that Poland, the Kingdom of Yugoslavia, the Soviet Union, Jordan, Syria, Turkey and Saudi Arabia all appeared in the aftermath of WWI.
Czechoslovakia, Yugoslavia and Poland
The Formed countries were: Estonia, Lativa, Lithuania, and Finland
None, they lost their New World Empire.
i know that the war in 1918 was in galipoli aganist Australian and new zealand

Austria, Hungary, Czechoslovakia
From 1984 or 1918? You put your question in World War I category (among others)...
Britan was one of New Zealand's allies in world war 2.
The League of Nations was formed at the end of WW1.
Countries formed after World War I were Poland which was reestablished after nearly a century, Yugoslavia, Czechoslovakia, Soviet Union even though it was an independent country before it was still a new country basically replacing Russia, Finland, Estonia, Lithuania, Latvia, and Turkey.
United Nations
Excluding the three Baltic states, they are: Russia, Belarus, Moldova, Ukraine (new European countries); Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Azerbaijan, Armenia and Georgia.
They were formed trading alliances
Some of them were "profits and gains". Well the superpowers at that time want to gain credit for war and therefore they primarily split Germany into smaller countries. (Which has similarly done after WW2) The others were some independence movements if I am not wrong.
