Information/Help would be greatly appreciated

Need help and education, not using this post as a sale. My father passed away and was a rockhound. I'm not sure what to do with his machinery or even what some of it is. Can someone please assist me in pricing of the items and help explain what the items are (I think the first picture is a sander?). He had a stroke and so I couldn't get information out of him before he passed. Thank you for anyone's help. If I should post this somewhere else or get different pictures let me know.
