Can you use it as a debit card and get money?

It would help if you were more specific about what "it" is.

You can get a cash advance on a credit card, but there's usually no grace period on cash advances (as there is with purchases) since the credit card company doesn't make any money on the transaction itself in that case.

If "it" is an EBT card, you may or may not be able to depending on the type of benefits. For cash benefits, you can usually make cash withdrawals. For "food stamp" type programs, you usually can't.
