How can I connect a Shelly 1PM with 2 way switch?
Supposing that in the location where I have to place the shelly I don't have the phase (L) from the circuit but I do have a phase from another circuit could I use it to power the shelly?

no you can't, only from the same circuit.
But is it possible using a shelly 2.5?
no, all shelly's need the same circuit (from same breaker, same phase)
