The first picture is that of Mealy Bug. If it is not much, I suggest using a strong jet of water to remove it. Most of the pesticides are ineffective against them.

For the remaining pictures, did you apply some kind of Fertilizer/pesticide foliar spray?

if there is no foliar spray done, then i feel it is sun scald. Sun scald is excessive light and heat build up (happens especially on wet leaves). Do you water the plants from the top.. i mean do you wet the leaves? water them in the evening and try it out. moving it to a shaded place will also help.

Watering on top can result in the heating up of leaves. water in the evenings till the summer is on.

I am not from Trichy but i have been there several times. I am from Chennai.
