Yes.

Do you mean VIN on the power header, or are you calling the barrel jack connector VIN?
The power header is after the reverse polarity protection diode, that diode has a 1 amp limit.
If you connect before going into the barrel jack there is no limit.

It would help to be more specific about these devices. What are they? Motors? Lights? Relays? And some technical specs would help.
