no she can not claim herself. . from the info you provided it would appear that dad had the right to claim her. under the tax laws.

he provided more than 1/2 her support (based on her income being only $5200)
As your daughter is under 19, she can be claimed as a dependent by her father.
If she files her tax return, she has to indicate that she can be claimed as a dependent by someone else. She will not be eligible for the stimulus payment.
