Is it right to connect the (-) from the diffirent signals in one common (-) to the analogue card? Will this connection may damage the analogue card?

If all signals have the same grounding, the connection will be ok. But be careful, if the supplies have different ground potential, it could produce a short circuit. I hope this helps. Best regards.
