Moreover, Why the normally hold in contact is connected in parallel with the start button?

The purpose of the hold in contact is to provide a current path through the relay coil when you release the start button. That is why it is wired in parallel with the start. Similarly, the stop is wired in series to break the relay circuit and hence stop the motor.

Secondly, How do you wire an open Close stop switch?

Connect each open button (opposite of the common side) to the open terminal of the operator. Connect each close button (opposite of the common side) to the close terminal of the operator. Connect the common side of one of the 3-button control stations to the common terminal of the operator.
