I've done #5 before. It didn't seem foolish at the time. Hardest part was climbing up the loader arms to the bucket to get to the ladder. Let's see; if the ladder is too short, and the farmhand loader is right handy, and there has been vast quantities of Coors consumed..............yup, worked for me.
#6 looks like something MacGyver would do. I don't think that is the OSHA-approved way to do things, though.
#8, the backhoe ascending the rail car,...now that was slicker than teddy-bear poop.
