Can i use same mosfet number for Upper and Lower side MOSFET in PWM Circuit? Because I always see different mosfet number ( for example Laptop CPU V_Core used MDU1511RH mosfet and MDV1525URH mosfet ) and why?

Depends on gate driver circuit.

Circuits can use same or complimentary pairs depending on how gate driver is done.

If same usually that requires a boost circuit to get upper mosfets turned on hard.
