No lease agreement, nobody is on th lease?

Even without an official lease, the landlord acknowledged that he knew you were there by giving you the 24-hour eviction notice, thereby giving you the same rights of any tenant. Also, you should have receipts for your rent that will establish de facto tenancy. You can take him to court for attempting a "do-it-yourself" eviction, which is illegal everywhere. So long as your rent is paid and you have not committed certain serious criminal offenses that can be proven by police records, such as dealing drugs, you cannot be evicted without at least a 7-day notice to vacate the premises. The actual time varies by state. Google your state's landlord tenant law to research the law where you live.
