  We present Magellan/M2FS spectroscopy of four recently discovered Milky Way
star clusters (Gran 3/Patchick~125, Gran 4, Garro 01, LP 866) and two newly
discovered open clusters (Gaia 9, Gaia 10) at low Galactic latitudes. We
measure line-of-sight velocities and stellar parameters ([Fe/H], $\log{g}$,
$T_{\rm eff}$, [Mg/Fe]) from high resolution spectroscopy centered on the Mg
triplet and identify 20-80 members per star cluster. We determine the
kinematics and chemical properties of each cluster and measure the systemic
proper motion and orbital properties by utilizing Gaia astrometry. We find Gran
3 to be an old, metal-poor (mean metallicity of [Fe/H]=-1.84) globular cluster
located in the Galactic bulge on a retrograde orbit. Gran 4 is an old,
metal-poor ([Fe/H]=-1.84) globular cluster with a halo-like orbit that happens
to be passing through the Galactic plane. The orbital properties of Gran 4 are
consistent with the proposed LMS-1/Wukong and/or Helmi streams merger events.
Garro 01 is metal-rich ([Fe/H]=-0.30) and on a near circular orbit in the outer
disk but its classification as an open cluster or globular cluster is
ambiguous. . Gaia 9 and Gaia 10 are among the most distant known open clusters
at $R_{GC}\sim 18, 21.2~kpc$ and most metal-poor with [Fe/H]~-0.50,-0.46 for
Gaia 9 and Gaia 10, respectively. LP 866 is a nearby, metal-rich open cluster
([Fe/H]$=+0.1$). The discovery and confirmation of multiple star clusters in
the Galactic plane shows the power of {\it Gaia} astrometry and the star
cluster census remains incomplete.
