Are these tile easy and look good when they are put up and what place to get them at

Denna...You can usually get at Lowe's, Home Depot, etc. We had them in our basement but when we remodeled we removed because they are so lightweight and opening and closing doors caused them to "kinda flop up and down" with the draft of the doors. A heavier material is soooo much better but it is totally up to you.
Amazon gas a treasure trove of styrofoam ceiling tile, you can paint them, cut them and easy install:
