None of the Allied powers are likely to turn into a version of Nazism. It was very strange that the Nazis took power in Germany. Fascism is what you get when the traditional conservatives are discredited in a modern state. None of the western allies have traditional conservatives like that, and it would have been liberalism - not anything like the Kaiser - that would have been discredited. Russia is the only country that fits in that category, but it lacks the industrial base and modern culture.
Britain is unlikely to become fascist. It will probably not lose any land even in a scenario where the Allies lose World War I. It has a strong democratic and liberal tradition. It's possible that Labor might enter government a lot sooner though.
France could possibly have a right wing government, but it would probably be lead by Action Francaise. At worst, it would be a mild form of fascism that had much more support of Catholicism, less secularism, and perhaps a restoration of the monarchy. It would still likely be constitutional with some form of democracy so not even as authoritarian as Portugal or Italy IOTL. If there is some kind of civil war between right wing and left wing radicals though, we could see a radicalization of politics. However, given France's need to stay good with Britain, I don't see any dictator coming to power.
Italy will probably go fascist just as it did IOTL with winning WWI. However, Mussolini will likely be pro-French since both countries will be looking to regain lost lands.
Russia will likely be embroiled in civil war for several years and have much of its land taken away. If we Brest-Litovsk as a basis, it will lose not just Finland and the Baltics, but there will be independent Caucasus republics, and a German backed Ukraine and Belarus. There might even be an independent Cossack state in the Kuban. No matter who wins in Russia - either Bolshevik or Tsarist conservative, Russia will have lost its breadbasket and much of its industry. In either scenario, liberalism is likely discredited. If the Whites win, they are likely to be very conservative, but would like the industrial base to be modern enough to be fascist. They'd probably fall back to traditional Russian despotism and anti-semitic pogroms with some kind of self-strengthening movement that would be the closest thing to fascism IOTL. It would be more like Franco on a bad day than anything like Hitler though.
