I don't know any Bollywood movies to recommend but can recommend a free site Beamafilm that you just need your library membership number to log in to. It has a good selection of international and
art house films, old classics and documentaries.
They add new movies all the time. I could only find one Indian movie but it wasn't a true Bollywood one.
Worth checking the site in case they add a Bollywood movie.
One of the Indian restaurants that we used to go to used to play movies back to back with music videos. If there's a
local Indian restaurant you could call in and ask the staff for recommendations of titles.
You could also search IMDB for famous Indian actresses and actors and look up their movies.
Once you have a list of the most popular actresses/actors you could search for their movies on you tube.
