Yes she can. She can file for a restraining order and include a kick out order in the restraining order. Given the situation, I would suggest that she hire a lawyer who can advise her as to how to proceed. I'm sorry that your friend is going through this.
Has he ever hit her? If so, she could have him removed permanently through a domestic violence petition. She should learn about that and take appropriate action to ensure her own safety and freedom from abuse. It requires an actual battery of some sort, a hitting, pushing, kicking, throwing something at her, etc. She should consult with a family attorney in the area in order to find out what she can do beside attempting to evict him.
File a domestic violence injunction is one possibility, but I am more curious as to the fact that it is not his home? If it is not his home, there is no lease, he does not pay rent, he is not on the mortgage, etc., then contact law enforcement and tell them he is trespassing. Ultimately it may not work, but it is a start -- also recommend contacting an attorney in the area to assist with this process. Things move quicker when an attorney gets involved.

If your friend in unsuccessful in obtaining his removal through a Petition for Protection Against Domestic Violence then she will need to evict him and based upon what you have stated he would be considered a month to month tenant and must be evicted as such.

If he has committed 2 incidents of assault, battery, or stalking as defined by the Florida Statutes within the last two years, then she should consider filing a Petition for Injunction for Protection Against Domestic Violence (i.e.- a restraining order). One of these domestic violence incidents of assault, battery or stalking must have occurred in the last 6 months. Otherwise, you will need to evict him. He would be considered a month-to-month tenant under an oral lease. Either way, I strongly recommend that she hire a lawyer to help her out with the very difficult situation. Good luck!
