AFAIK, you can't use Geonames data in OSM. Geonames get data from anywhere it can, and doesn't meet the OSM license requirements. See osm.wiki/index.php/Geonames
As always for new data sources, if it's not mentioned that is ok to use on the wiki, bring it up on the legal mailing list to verify it's fine to use.
