Heavy quark symmetries are useful for predicting the existence of heavy states, their masses, and spin states. Despite numerous studies on the \(P_{c\bar{c}}(4440)\) and \(P_{c\bar{c}}(4457)\) heavy states, their spin states have not been previously determined. In this study, heavy symmetries are applied to predict the spin states. If the \(P_{c\bar{c}}(4440)\) and \(P_{c\bar{c}}(4457)\) states are considered \(\bar{D}^*\Sigma _c\) molecules, they can be classified as heavy partners. This classification may help clarify their potential connections with heavy antiquark-diquark symmetry partners. By utilizing these alternative spin assignments and the concept of heavy antiquark-diquark symmetry, it may be possible to estimate \(\Xi _{cc}^{(*)}\Sigma _c^{(*)}\) states, and ultimately, their spin states, which have not been elucidated in experiments. In addition to these symmetries, the relationship between \(P_{c\bar{c}}\) and \(P_{c\bar{c}s}\) pentaquarks can be constructed which supports the prediction of possible \(P_{c\bar{c}s}\) states. The predicted masses of the \(P_{c\bar{c}s}(4338)\) and \(P_{c\bar{c}s}(4459)\) states align with several studies, allowing us to eliminate a specific spin state. One spin state appears to be favored, suggesting that \(P_{c\bar{c}}(4440)\) has \(J^P=\frac{1}{2}\) and \(P_{c\bar{c}}(4457)\) has \(J^P=\frac{3}{2}\) .
