Third and fourth from the bottom ( up) is /are likely to be quartz/quartzite that was fracured under pressure and re invaded by more whiter quartz. The last looks to probably be quartzite too, but much more stratified from its intial formation - again secondarily striped due to reinvaion of fracture is possible origin of contrast. Tom toss the last one and work with the others.
