We investigate vortex solutions in the Ginzburg-Landau theory for neutron$^3P_2$ superfluids relevant for neutron star cores in which neutron pairspossess the total angular momentum $J=2$ with spin-triplet and $P$ wave, in thepresence of the magnetic field parallel to the angular momentum of vortices.The ground state is known to be in the uniaxial nematic (UN) phase in theabsence of magnetic field, while it is in the $D_2$ ($D_4$) biaxial nematic(BN) phase in the presence of the magnetic field below (above) the criticalvalue. We find that a singly quantized vortex always splits into twohalf-quantized non-Abelian vortices connected by soliton(s) as a vortexmolecule with any strength of the magnetic field. In the UN phase, twohalf-quantized vortices with ferromagnetic cores are connected by a linearsoliton with the $D_4$ BN order. In the $D_2$ ($D_4$) BN phase, twohalf-quantized vortices with cyclic cores are connected by three linearsolitons with the $D_4$ ($D_2$) BN order. The energy of the vortex moleculemonotonically increases and the distance between the two half-quantizedvortices decreases with the magnetic field increases, except for adiscontinuously increasing jump of the distance at the critical magnetic field.We also construct an isolated half-quantized non-Abelian vortex in the $D_4$ BNphase.
