Actually, I'm seeing some red flags for Autistic Spectrum Disorder or A.S.D. Combine even high functioning A.S.D with its difficulty with transitions and fixations, with the current unstable living situations, and you've got fertile ground for rages.
My suggestion is to get this child in for a full neuropsychological evaluation (8 hours or so) asap. If he is autistic, or even bipolar, interventions MUST be started asap.
Treating Bipolar requires medications, usually heavy duty medications. There is no medication that cures Autism, but some medications are used in autistics to deal with the overwhelming anxiety many of us feel just from dealing with what you, as a neurotypical person, find to be normal and not even worthy of consideration.
Best of luck. Do keep in touch and keep us posted on how your son is doing. We are a wealth of info though know our limits. You will find many parents who have gone through what you are going through and I'm sure, after the weekend (it's slow then), several folks will stop by. We also have strong shoulders and warm hearts.
In the meantime, do create a signature that lists your son's (supposed) disorders, what medications he is on, and anything else that you think would help us keep track of you and him.
Also, many of us are in the 40-65 age range. That means our eyesight isn't what it used to be (mine has always been awful) and walls of text are hard to read.
Could you please break up your future posts into smaller paragraphs? It makes it easier for us older folks to read your posts.
