TMK, hematite is never white or clear-white (like quartz). I think what you've got are some metamorphic rocks with some iron content.
TBH, the two samples circled below look
more like hematite than the samples you've been asking about, and I can't even be sure about them.

It's very difficult--nigh impossible--to definitively identify rocks/minerals by photo alone. This is why geologists/mineralogists use
other tests

to identify/confirm.
Hematite is one of the most abundant minerals on the planet. Is there some particular reason you're pursuing it?
