This shouldn't be that hard. All you need is for the Ottoman empire to stay neutral in WWI. This should be sufficient enough for the Ottoman empire to stay somewhat intact, and shouldn't cause enough butterflies to deny the rise of fascism in Italy, Japan, and Germany, and the Soviets in Russia.
So for scenario 1, 3, and 4 all you need is Germany to force the Ottomans to join the axis in the way that they almost did to Turkey in otl. Alternatively the Germans could simply invade and put up a friendly government without too much difficulty as well (a.k.a. atl Mediterranean strategy)
For scenario 2 and 5, all you need is for Germany to invade, Ottomans don't collapse as easily and has enough time to create a alliance of convenience with the SU and/or allies, so you have a Ottoman Empire allied to either the SU or the Chinese.
If you want a alliance with, say, just the Germany and Ottoman and no one else, then I'm at loss.
