Q: Will 24" 2009 Cinema Display work with new MacMini 4 (2015)?

Your help with my Cinema Display with MacMini matchups would be very much appreciated! If I purchase a new Mac Mini I first would need to know the following:

1) Will my 2009 24" Cinema Display work with the new Mac Mini 4 (2015)? and

2)  Will my 2005 20" Cinema Display work with my Mac Mini 2 (2009-Leopard)?

Thank you very much for your time and expertise!
