They all will work. They all have pros and cons. It would be wisest to pick the steel that best fits your forging/grinding/HT abilities.
52100 will get hard and sharp. At the length of a tulwar, it may need to be tempered down a good bit to avoid breaking.
5160 or 9260 will be very tough at normal hardness.
1085 is easy to work and HT. It is hard to beat as a general sword steel.
If I was making it, I would probably use 1070.
