"Can you share a neutral with three different single phase loads for example cccts 1,3,and 5 from a 3 phase load center? Lets say the the single loads are are three different receptacles. So can I pull a red, black and blue with one white wire to all threeand have each circuit share that neutral?"
Yes you've created a 3 phase network. You would have to add a green wire if you really want to earn a gold star!
