Before reading any of the replies, I reviewed your list and had the following thoughts. NOTE: I am still learning also.
Any of the Blockchain names have a shot at selling as more and more companies are looking to implement blockchain to meet their needs (it's not just for crypto currencies). If they were picked up at/near registration fees, I think they would be a good add to a portfolio (just selling one of them could be a huge win). When I saw BlockchainGraphs.com, I thought that was a nice name, and actually thought with blockchain, perhaps "graphs" is a better fit over "charts" if only to be "different" and sound like really cool technology. Company-X offers BlockchainCharts, but Company-Y offers BlockchainGraphs....
I thought FlyXD had real good potential in the Drone Space.
ReThrill was interesting. I thought Brandable name to bring back the "thrill"...
I could not think of an immediate use for the other names, but they could be brandable in some way.
I believe for the names I specifically mentioned, if they showed up in GoDaddy's expired Names Auctions then most (if not all) would be purchased during an auction with multiple bids, or as soon as they hit GoDaddy Closeouts. But that is just my opinion. As you said, one man's meat is another man's....
