You need to take advantage of Lagrangian Points.

Whenever one massive body orbits another, there are five points surrounding them where other massive bodies will be in equilibrium, in terms of gravity, with the first two bodies and with each other.

Several of Jupiter's moons orbit at each other's L4 and L5 points, including the trio of Calysto, Telesto, and Tethys. These three objects could be said to be, loosely speaking, at rest with respect to each other. If in addition, all three were tidally locked to Jupiter, meaning they always show the same face to Jupiter, they would also always show the same face to each other.

If three moons can do it around a planet, it isn't hard to image that somewhere there are three planets doing it around a star.
