How many credit cards should you have to rebuild credit?


I’m trying to rebuild my credit after identity theft, some of the problems were my years of principle and not loans that have been reported. (I mainly use my debit card and pay cash for everything). I make good money now and I am trying to build up to buy a home within the next few years. My good accounts (rental, club, cable, cellular, etc.) are not reported my good credit. How many cards should I take that will help my credit score increases, not hinder my credit. Thanks!
