Flower - Macro Photography

What type of flower is this called?
I took these shots in Compound close to my friend's home when I went to visit him. This is quite different from my previous flowers which are mostly yellow. It is more of a white with a little yellowish color inside.

There are some drops of water inside it when looked closely. The greenish one by the side is still in its infant stage
