Here is the reply I got from another board:
"The top two look like red granite, which is basically granite with different components (alkali or iron-rich feldspar.) The banded ones are gneiss, which is basically highly compressed, metamorphasized granite."

those are gorgeous! the lighter colored rocks in all of them seem to have been shattered and in the case of the bottom photo, they look like they were melted at some point especially the second to last one, maybe before they got included in that wonderful red melt matrix. bottom inclusions look like feldspars, I don't know what makes rocks red out there, Iron? that deep deep red really makes the inclusions stand out. I would be tempted to say explosion breccia of some sort on the 2nd from the bottom. wish I could handle them and put them under my giant magnifier. Maybe granite, maybe gabbro, the banded one makes me think of feldspars I find here,the first one looks like a pegmatite, or coming close to it, with the crystals being so big. those would all make super cabs or display pieces.

I can send you some if you want to examine them and play with them.

I'm saying all are granite, even the stripey one. Mylonized granite.
