  We investigate the observed pentaquark candidates $P_c(4312)$, $P_c(4440)$
and $P_c(4457)$ from the latest LHCb measurement, as well as four possible spin
partners in the $\bar{D}^{(*)}\Sigma_c^*$ system predicted from the heavy quark
spin symmetry with the hadronic molecule scenarios. Similar to the previous
calculation on $P_c(4380)$ and $P_c(4450)$, the partial widths of all the
allowed decay channels for these $P_c$ states are estimated with the effective
Lagrangian method. The cutoff dependence of our numerical results are also
presented. Comparing with the experimental widths, our results show that
$P_c(4312)$, $P_c(4440)$ and $P_c(4457)$ can be described well with the
spin-parity-$1/2^-$-$\bar{D}\Sigma_c$, $1/2^-$-$\bar{D}^*\Sigma_c$ and
$3/2^-$-$\bar{D}^*\Sigma_c$ molecule pictures, respectively.
