Sure. How you proceed depends on what you want to learn. You can treat
one ligand as the 'ligand' and the rest as part of the 'receptor'. You can
treat all ligands as one collective 'ligand' and the receptor as the
receptor. The first approach is probably more reliable than the others
(especially if there is cooperativity in the different binding events
associated with conformational allostery).

Good luck,
