My baby girl 's weight is 6.5kg and she will complete her 8th month on 5th of September.... is the weight is less? And What food can be given to increase her weight?

You can give mashed bananas to ur baby for increase in weight

Hi do not worry about the weight part if your baby is active and achieving milestones, include good fats in her diet regularly like unsalted butter, ghee, coconut oil, banana, potatoes, avocado, nachini etc.
