My current setup is a 2015 5K iMac which has 2 HP monitors setup for a 3 display split. Unfortunately these two displays take up both of the Thunderbolt ports on the back. Im looking at buying a storage array that will hook up via thunderbolt 2. What solution could there be to add this mass storage array with the nice speeds of thunderbolt 2 without losing one of my displays.

Or buy a Thunderbolt drive with an extra TB port and daisy chain one displays thru it.
Thunderbolt supports daisy chaining. https://www.macworld.com/article/2146360/lab-tested-the-mac-pro-daisy-chain-challenge.html
Get a RAID storage box with dual Thunderbolt-2 ports and connect one port to the iMac and the other to one of the displays. Alternative go with the thunderbolt dock suggestion.
It sounds like you need a Thunderbolt dock. I'd recommend reaching out to www.macsales.com and they can help you to see if what you want/need is available.
