Newts can go without food for a long time. 4 days is nothing to worry about. In fact, when temperatures are normal for my newts I don't feed my newts every day. And when temperatures are lower you can feed them even less.
When they are in a new setup I'd give them time to adjust. Don't handle them, don't put too much light on, keep the water clean (remove uneaten food). They'll probably be fine after a while. Just keep an eye on them to be sure.

Many questions you may have now or later will be answered there.
Good luck
