Shari’ah permits males to have a maximum of four wives simultaneously on condition that he maintains equality and justice among all his wives. Therefore, a female can be the second wife.
However, due to the sensitive nature of becoming a second wife and the implications on the subsisting marriage, one should exercise extreme precaution.
And Allah Taãla Knows Best.
