First thing is who has the mill and what type of mill? Second would be mill them asap as sitting around will not do anything positive for you.
If they were mine, I would straighten out the butt flares & cut off the ends where they flare out from branching. This leaves you straight logs, easier to mill. Then I'd quarter saw them to 4/4. The things I would look out for is the very first log, which I would probably mill plain 10/4 slabs from, and the last log that has metal in it will tear up your saw if you don't avoid the metal. Quartered white oak is stunning. That's just me, if they were mine.
But they're not mine. You'll need to decide what you will most likely use the lumber for and saw accordingly. It looks to me like that was a yard tree and some of those logs are maybe large branches. Tough to tell from the pics but that's what it seems to be. That may make drying a little more difficult. If you quarter saw, you shouldn't have any trouble drying. You wouldn't hurt to sticker it & let it air dry a few weeks before sticking in the kiln. Should dry ok.
