Four decay modes of the $${B}_c^{+}$$ meson into a J/ψ meson and multiple charged kaons or pions are studied using proton-proton collision data, collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV and corresponding to an integrated luminosity of 9 fb-1. The decay $${B}_c^{+}$$ → J/ψK+K-π+π+π- is observed for the first time, and evidence for the $${B}_c^{+}$$ → J/ψ4π+3π- decay is found. The decay $${B}_c^{+}$$ → J/ψ3π+2π- is observed and the previous observation of the $${B}_c^{+}$$ → ψ(2S)π+π+π- decay is confirmed using the ψ(2S) → J/ψπ+π- decay mode. Ratios of the branching fractions of these four $${B}_c^{+}$$ decay channels are measured.
