One SPI master can talk with many SPI slaves by managing the CS lines appropriately. Each slave should have a different CS. Pull down the CS when you want to talk to that slave and set it high after you're done.
If you want to talk to each slave at the exact same time, with different data, then of course you'll need a different SPI for each.

can we connect the three SPI with single SPI block, while use the GPIO for CS and SDO. note: SDO is unidirectional.
