does the no in the star 2 effect the income???

Sorry I don't exactly know, but looking from other members who have star of 10 or 9, and knowing their income, it seems like the stars doesn't have any effect. In my own experience, each post I did earns around $0.017, which is relatively the same with earnings when my star is lower. If you don't mind, you can check your earnings and divided with your posts, and tell me whether your number is ± $0.017 per post.
