Looking at the horoscope matching we see that the Ashtkoot Guna milan score is 20.5 which is higher then 18 that is required for marriage. There is Gana dosha as the girl belongs to Rakshasa Gana. The grahmaitri score is also weak.
Regarding mangal dosha we see that the girl has Mangal dosha, while the boy is not mangalik. Mangal dosha of the girl gets cancelled as Mars is Yogakarka planet in the horoscope.
However as the Gana dosha is there and Grahmaitri score is less. It is recommended that you do Grah Milan (Matching of the Planets) before you take any decision.
It is important to look at Guna as well as Grah milan before you solemnize marriage.
