It is correct to keep the name ‘Masood Abdullah’ in case it is a boy. It means blessed and fortunate. It is also right to keep the name ’Hena’ in case it is a girl. It means Henna. But its next part Manha is meaningless hence you should not keep it as name. If you keep any other name amongst the following names then it shall be far better: Ayesha, Hafsa, Ruqayya, Kulsum, Fatima, Juveriya, Khansa etc. It is mustahab to name the child on the seventh day of its birth, to shave its head, and give gold or silver equal to its hair in charity as well as do aqiqah of two goats in case it is a boy and one goat in case it is a girl.
Allah (Subhana Wa Ta’ala) knows Best
