I think not A. tortuosum
First image is Arisaema caudatum Engl.
Second one is Arisaema tortuosum var. neglectum (Schott) C.E.C. Fisch.
third and fourth I suppose a plant from the same population with some variation???
This looks more like Arisaema neglectum, a species that can also be found near the Fort at Sinhagad near Pune. Tortuosum is bigger with usually more than 1 leaf and the leaf has a substalk (rachis) on which the leaflets are positioned whereas the leaflets of neglectum seems to originate from a single point.
