It looks like you have 1 low side switch and 3 high side (non grounded) switches. That will take 3 IR2110 chips.

IR2110 bootstrap supply can't work for S1 and S2 (presumed your driver supply and input signal is referred to VH-). You'll need at least a second floating driver supply voltage. There are additional questions, e.g. does the "mid" voltage node tolerate DC bias currents of the IR2110 driver?
