This animation shows some of the movements the engines can pull off https://www.reddit.com/r/SpaceXLounge/comments/kf25kr/starship_raptor_gimbal_visualized/ https://www.reddit.com/r/SpaceXLounge/comments/kf25kr/starsh...
In the recap video they are only using two engines though. I think on SN15 they relit all 3, and then the guidance computer picked either the two most stable (in the case one of them didn't relight properly), or the two with the best lever arm for the landing trajectory, then shut the remaining one down. Earlier landings tried just one (I think there's enough thrust and maneuverability to do it) but there was no redundancy if it failed.
