Although resonant planets have orbital periods near commensurability,resonance is also dictated by other factors, such as the planets'eccentricities and masses, and therefore must be confirmed through a study ofthe system's dynamics. Here, we perform such a study for five multi-planetsystems: Kepler-226, Kepler-254, Kepler-363, Kepler-1542, and K2-32. For eachsystem, we run a suite of N-body simulations that span the full parameter-spacethat is consistent with the constrained orbital and planetary properties. Westudy the stability of each system and look for resonances based on thelibration of the critical resonant angles. We find strong evidence for atwo-body resonance in each system; we confirm a 3:2 resonance betweenKepler-226c and Kepler-226d, confirm a 3:2 resonance between Kepler-254c andKepler-254d, and confirm a three-body 1:2:3 resonant chain between the threeplanets of Kepler-363. We explore the dynamical history of two of these systemsand find that these resonances most likely formed without migration. Migrationleads to the libration of the three-body resonant angle, but these anglescirculate in both Kepler-254 and Kepler-363. Applying our methods to additionalnear-resonant systems could help us identify which systems are truly resonantor non-resonant and which systems require additional follow-up analysis.
