yes at night corals will change soft corals will sometimes shrink or shrivle up . some hard corals will let out feeding tentacles or sweeper tentacles as well. and some corals will only truly open at night.
That is VERY natural, yes. 
As long as your corals look very open and healthy during the day, they're probably doing fine. Make sure to have a consistent schedule of lighting in your tank by using timer.
