Majority of them are swirls and some of them are deep scratches. Swirls could be removed easily using compound and polish, but I suggest not to go after deep scratches because that will require lot of paint removal due to compounding.
If you don't want to compound, then another option is to use glaze or waxes with heavy fillers.
Are you planning to fix it by yourself? If yes, then do you plan to use a polishing machine, or by hand?
