Common name: China Aster  
This is an occasional ornamental in Pantnagar to which I suspect as Callistephus chinensis.
Kindly validate or otherwise.

The last picture ( DSR_4.JPG) is one of the Chinese asters, C.chinensis for sure. I have this plant in my house. The other pictures also look like varieties of C.chinensis only. The species has considerable number of varieties in different colours.
