Unmapped fields are fields in Marketo that are not synced to a field in SFDC. If the custom fields are used in smart campaigns then they will be updated, it just means there is no field on the SFDC side to view this info. Most custom marketing-use fields have no need to be on the SFDC side, so we just keep them in Marketo.

This means that these fields are not mapped to SFDC. Not an issue unless you want those fields to be passing data to the matching field in Salesforce.
Check out this documentation:
Again, this isn't an issue if the fields in this folder are intended to be used and accessible ONLY in MKTO and not in SFDC. If you want these fields available in SDFC, you need to create the field in SFDC and map the fields.
The custom field ( that I am using) and showing up in " unmapped custom field" is on CONTACT object type.
For CONTACT object type- sync is directional.
If any salesperson changes the value of the custom field( that I am using and showing up in unmapped) in SFDC, Will that be updated in Marketo?
I would assume those edits that Sales is making are not passing into MKTO. I would run a simple test to determine if this is True or not, but based on what I know sounds like those values are not passing because the field is not mapped to SFDC.
