what is dns settings for custome domain?

You mean for applications? I basically set an A record pointing to my Puffin instance's IP. I wouldn't point to demo instance at puffin.rocks, but a personal one.

my wordpress app address is http://wordpress.mariaregan.puffin.rocks/. How to change it to my domain? There is a settings button for the app. But, I dont know what to add in my domain A record or DNS? If A Record means, what is the IP for that?

As said, I don't recommend hosting your real Wordpress on puffin.rocks, since I might occasionally delete all the data (it's a demo platform).

However if you want to try it, then enter your domain name in Puffin settings. Then create an A record using your DNS service pointing to puffin.rocks IP (exec ping puffin.rocks to learn the server IP).
