  The exploration of magnetic topological insulators is instrumental in
exploring axion electrodynamics and intriguing transport phenomena, such as the
quantum anomalous Hall effect. Here, we report that a family of magnetic
compounds Eu$_{2n+1}$In$_{2}$(As,Sb)$_{2n+2}$ ($n=0,1,2$) exhibit both gapless
Dirac surface states and chiral hinge modes. Such a hybrid-order topology
hatches surface-dependent quantum geometry. By mapping the responses into real
space, we demonstrate the existence of chiral hinge modes along the $c$
direction, which originate from the half-quantized anomalous Hall effect on two
gapped $ac$/$bc$ facets due to Berry curvature, while the unpinned Dirac
surface states on the gapless $ab$ facet generate an intrinsic nonlinear
anomalous Hall effect due to the quantum metric. When Eu$_{3}$In$_{2}$As$_{4}$
is polarized to the ferromagnetic phase by an external magnetic field, it
becomes an ideal Weyl semimetal with a single pair of type-I Weyl points and no
extra Fermi pocket. Our work predicts rich topological states sensitive to
magnetic structures, quantum geometry-induced transport and topological
superconductivity if proximitized with a superconductor.
