If I understand the seasons in India correctly, you have already been through the rainy season. Don't wait until the next rainy season to get the problem with your drainage fixed. Now will probably be the ideal time to get it fixed. Please get someone who will tell you what to do and then have the work done. The paint on that wall in your beautiful home will keep coming off!

If you want to remove the paint, you can rent a sandblaster and test it out; the main thing you want to watch for is if it is damaging the mortar. Otherwise, you could add sand to paint and either paint it all one color, or do a faux finish on each stone with a blend of several colors, I would start with one color base coat you want the mortar color to be and then move to the stones. Another idea is to call a stucco company and see if they can give you a smooth finish.
