I use latest version of leaflet 1.5.1. I know than can reproject WMS layer but if i want to change project of TileLayer like Google Maps or OpenStreet.. It is possible to do this?
No, Proj4Leaflet can't do raster reprojection, which I think is what you want. The purpose of the plugin is to support other projections than those built into Leaflet.
