Do the stairs off my french doors need to be the width of both doors or can they be just the width of the most used side?
How big does the landing have to be at the top and bottom?
Can I just attach a guardrail to the exterior and forgo the stairs?

If the door can be opened, it must have a landing on the outside, minimally 36"X36", but in your case, it must be the width of the doors X 36" deep from the house. You can put a guard rail in front of the inactive one, then have a smaller landing. That will look a little odd in my opinion though.
Model building codes rarely have exemptions for less used doors. However, a myriad of model building code compliant configurations is possible provided that among other things:
The overall configuration of doors and stairs complies with all the requirements for landings at both doors.
The overall configuration complies with the requirements for guards and handrails.
Keep in mind that to be code compliant, the construction must meet all the requirements of the code, not just selected sections.
I can't speak for specific codes but have remodeled houses in at least 15 different counties and a few countries. No inspector would ever let me have french doors opening to either a drop-off or guard rail. There is exactly no way around this. You must have a proper step off on all doors, whether they will be used or not.
If you don't want wide stairs than I suggest that you create a small landing area - at least one foot wider than the width of the doors - and then do the steps on the side you want. I know that this may not work with your surroundings but you haven't let us know the whole layout.
