We perform classical Monte Carlo and stochastic Landau-Lifshitz-Gilbertsimulations to study temperature dependent magnetism of Kagome antiferromagnet(AFM) Weyl metal $\text{Mn}_3\text{Ge}$ and find that a long range chiral ordersets in at a transition temperature well below the N{\'e}el temperature($T_N$). Based on the crystalline symmetries, imposed by the chiral magneticorder, we argue for the presence of multiple iso-energetic Weyl nodes (nodesthat are at same energy and with congruent Fermi surface around them) nearchemical potential. Using the semi-classical Boltzmann equations, we show thatthe combined contribution to the net longitudinal magnetoconductance (LMC) andthe planar Hall conductance (PHC) from tilted Weyl nodes can lead tosignatures, qualitatively distinct from that of a single pair of Weyl nodes. Inparticular, we show that magnetic orders with different chiralities can giverise to different periods in LMC and PHC as a function of the in-plane magneticfield direction. This is ultimately related to differences in thesymmetry-imposed constraints on the Weyl nodes.
