All the spots look like where branches have been cut off, and would show up as knots in a bow any way. If you are a experienced splitter, split them into staves, the knots and radial grain will usually take care of themselves. The bows will have character, character staves are better than no staves, if the wood is not perfect.
If you sawed them into staves its likely that you'd sever knots on the blind side, probably lose some staves. Bad bits can be shortened, turned into billets, 34-42" long.
You can thin the sapwood down on split staves a bit to avoid any divits, or back them with hickory when they are dry. Don't waste the "totally damaged side" until you have split the log, it will be useful for something, even if it doesn't make a bow.
