Is it ok for a 14 year old girl to masturbate a lot?

Yes & No - Reasons?: Perhaps a bit usual; also exploring self. Probably the larger issue is the reasons. While there is no evidence that mastubation is harmful (despite old social taboos) a larger concern might be the situation & why such a drive for some pleasure. Could it be that person's view of life & issues depressing, feels trapped, bored & looking for some form or relief/pleasure. Suggest exploring other issues.
