Baahubali 2 will be at 1st even without China release most probably until unless it is rejected. 700cr in India and $35mn Overseas 1st phase is what I expect.
Taiwan nothing reported on Rentrak so far for Dangal. Let's wait for official update.
As for Dangal China, I don't know exactly when it's advance opened but currently it's out of Top 10 on May 5 advance in China.
