name_1 is old and should be replaced with alt_name.  You can add multiple alternative name values by separating them by a semi colon (;).  There's also old_name for when a street is renamed and official_name which I only use for otherwise unnamed ramps.

Tiger tags are also no longer used, although the only one I routinely delete is the reviewed one.

Stuff like this is what makes mapping challenging.  You can use plot addresses and the NJ Arcgis Centerline as tie breakers.
