Canon M6 has a Canon EF-M lens mount and currently there are 12 native lenses available for this mount.
M6 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on M6.
Since Canon M6 has a APS-C sensor, it has a focal length multiplier of 1.6× so you have to multiply lenses original focal length with this multiplier to find the Full Frame equivalent focal length of the lens when mounted on M6.
