Which digital pins to interface to LCDs, RFID, etc? Arbitrary? Aside from PWM)

Hey community,

I see in diagrams for the LCD and RFID reader that I'd like to use, that they both use digital pins 9-13. Aside from performing PWM, is it okay if I just reassign which pins will be used so I can fit them to the same Uno board?

Thanks for any input.

Are they both using the hardware SPI? Then both need to connect to 11-12-13, and different pins can be used for 9-10. Like 5-6 if PWM is needed.
