By studying 7 objects in the Lupus clouds we aim to test if a coherenceexists between commonly used evolutionary tracers.  We present ALMA observations of the continuum and molecular line emissionthat probe the dense gas and dust of cores and their associated molecularoutflows. Our source selection in a common environment allows for a consistentcomparison across different evolutionary stages.  The quality of the ALMA molecular data allows us to reveal the nature of themolecular outflows by studying their morphology and kinematics. The images inIRAS15398-3359 appear to show that it drives a precessing episodic jet-drivenoutflow with at least 4 ejections separated by periods of time between 50 and80 years, while data in IRAS16059-3857 show similarities with a wide-angle windmodel also showing signs of being episodic. The outflow of J160115-41523 couldbe better explain with the wide-angle wind model as well, but new observationsare needed to explore its nature. We find that the most common evolutionarytracers are useful for broad evolutionary classifications, but are notconsistent with each other to provide enough granularity to disentangledifferent evolutionary stage of sources that belong to the same Class. Outflowproperties used as protostellar age tracers (mass, momentum, energy, openingangle) may suffer from differences in the nature of each outflow, thus detailedobservations are needed to refine evolutionary classifications. We found bothAzTEC-lup1-2 and AzTEC-lup3-5 to be in the pre-stellar stage, although thelatter could be more evolved. IRAS15398-3359, IRAS16059-3857 and J160115-41523,which have clearly detected outflows, are Class 0 sources, although we are notable to determine which is younger and which is older. Sz102 and Merin28 arethe most evolved sources and show signs of having associated flows, not as welltraced by CO as for the younger sources.
