Steele,
Sorry about the delay, I've been out most of the day. Here's my take on these. As a photographer you know what lens flare is. And in my honest opinion these appear to be lens flare due to some light source out of the frame. And the blue-purple shade is actually quite common for lens flare due to the coating on higher grade optics.
I fully understand the need to protect the subject of the photo, as I do understand that this was not taken as part of a paranormal investigation. If you look through some of your other pictures, I'm willing to bet that you'll find some bright object directly in alignment with the "orbs".
