Yes, there can certainly be benefits to having more than one baby pillow. The reason for this is because every baby pillow is so different and each one serves different purposes. For example, you may want to get a good pillow to be used to support your baby's head while they sleep, as well as a great tummy time pillow. You could even add a good crib wedge pillow to get a good angle at night as well as a lounger pillow for your baby to hang out in when you need some hands-free time.
