Hi, welcome to OSM. Which OS maps/datasets are you using, and have you surveyed any of these roads in person before changing their classifications? Not all OS maps have suitable licences, although OS do release some open data and many older maps are now out of copyright. I haven't checked all of the changes made, but highway=unclassified was probably a better fit for Crag Road. Please see https://wiki.openstreetmap.org/wiki/Copyright_information_for_UK_mappers, https://wiki.openstreetmap.org/wiki/How_We_Map and https://wiki.openstreetmap.org/wiki/Roads_in_the_United_Kingdom for further info.
