You can replace the two smaller ones with 3 TB drives, and not lose anything.
Though given the small price difference between 3 and 4 TB, I'd probably just replace and failed 3 TB drives with 4 TB drives myself.
The RN100 series has a 16 TB cap on the volume size, so in theory you could go with 4x5TB, or even 2x6TB+2x5TB. However those drives are not on the compatibility list. Not sure why Netgear hasn't added them, since there is no technical reason why those larger drives won't work as long as you don't exceed the volume size cap.
