If i purchase more than 100 shares of Yes bank, will i able to sell all purchased shares or 75% of purchased share will get blocked?
You will be able to sell. The 75% block is only on the shares bought on or before 13th March, not after that.

As I said above, that restriction is only on shares purchased on or before March 13th, not if you have bought after that.
