All OpenStreetMap data are avivable for free. You can get raw data through overpass api via https://overpass-turbo.eu/ or QuickOSM plugin in QGIS. Also you can download some prepared dataset from OSM data - for example from http://download.geofabrik.de/asia/india.html but I don't know if these are detailed enough.
