From my experience and what I understand from reading manuals, it is totally fine to have phantom power on while using dynamic mics. It shouldn't cause any problems. Dynamic mics simply ignore the DC current from pin 2/3 to pin 1.

though dynamics neglect phantom it is not usually advised to
be careful to remove phantom before connecting or removing the mic else a spike can damage the diaphragm

thank you very much,
both of you

cheers

Could I savely use dynamics on the remaining 2 inputs (sm57 / md441u / d112) ?

Yes, as long as it is a balanced microphone and connection.
