Combine 2 WD120EFAX and 2 WD120EFBX drives

I have a My Cloud Pro Series PR4100 NAS with My Cloud OS 5 with Firmware 5.18.117 and 2 WD Red WD120EFAX 5400 rpm drives. I did not get another 2 discs of the same reference, but, they sell me 2 discs WD Red Plus WD120EFBX of 7200 rpm, … Can I combine both references ???

[to have all 4 drives in RAID 5]. Thanks.
