Yes, I believe so. You can add all the values (as long as all of them are in VA), and estimate the VA needed by the UPS. But since this value varies along time (sometimes the computer consumes more, someetimes less, sometimes it's the real power that changes, sometimes it's the reactive power), you need to be careful not to measure everything exactly in a moment when the consumption is too low, otherwise your estimated value will be incoherent.
