There is a bit of confusion in your wording, so I'm hesitant to give a blanket "yes".

The analog input module (sitting on top of the cRIO) are able to safely measure 5V. In fact, they are able to measure slightly higher voltages as well - their maximum is not 5V.

Many analog sensors will return a voltage in the 0V to 5V range, but there are others that do not. What specific sensors are you using?

Multimeters measure voltage (and other electrical measurements like resistance and current), but they are not typically used to create a voltage.

The digital sidecar does not have any analog inputs. They do have digital inputs.
