I don't think I'd use the 5 weight since it may be a little too thin for the how the engine is built. But any of the others you listed in the OP should be fine. The listing of only 20w-40 and 20w-50 is from older manuals (the service and owners manuals from '08-'11). The 2012 manual is updated but applies to all raiders since the engines are the same.
The 2012 service manual lists the following under engine specs:
Recommended Brand Yamalube
Lubrication System Dry sump
Type SAE 10w-30, 10w-40, 10w-50, 15w-40
20w-40, or 20w50
Recommended Engine Oil Grade API service SG or higher, JASO standard MA
