  We aim to investigate the global star formation scenario in star-forming
sites AFGL 5157, [FSR2007] 0807 (hereafter FSR0807), [HKS2019] E70 (hereafter
E70), [KPS2012] MWSC 0620 (hereafter KPS0620), and IRAS 05331+3115 in the outer
galactic arm. The distribution of young stellar objects in these sites
coincides with a higher extinction and H2 column density, which agrees with the
notion that star formation occurs inside the dense molecular cloud cores. We
have found two molecular structures at different velocities in this direction;
one contains AFGL 5157 and FSR0807, and the other contains E70, [KPS2012] MWSC
0620, and IRAS 05331+3115. All these clusters in our target region are in
different evolutionary stages and might form stars through different
mechanisms. The E70 cluster seems to be the oldest in our sample; AFGL 5157 and
FSR0807 formed later, and KPS0620 and IRAS 05331+3115 are the youngest sites.
AFGL 5157 and FSR0807 are physically connected and have cold filamentary
structures and dense hub regions. Additionally, the near-infrared photometric
analysis shows signatures of massive star formation in these sites. KPS0620
also seems to have cold filamentary structures with the central hub but lacks
signatures of massive stars. Our analysis suggests molecular gas flow and the
hub filamentary star formation scenario in these regions. IRAS 05331+3115 is a
single clump of molecular gas favoring low-mass star formation. Our study
suggests that the selected area is a menagerie of star-forming sites where the
formation of the stars happens through different processes.
