This depends only on your preferences; for example you can use 6-8 lbs.
Typically a serving is half a cup. There are about 4 servings in a pound of potato salad. That would mean 240 servings in 60 pounds.
To start with, you should never be putting mustard or vinegar in potato salad!! Yuck!!
Unless you have a recipe which substitutes the mayonnaise with something much healthier, then no...
Approximately 4.5 quarts in 5 pounds of potato salad, including hard-cooked eggs.
I would make 25 pounds of it.
That is 87.5 pounds
A bound salad is a salad made of hearty ingredients (meat, potatoes, etc.) fortified with a thick sauce (almost always mayonnaise). This is the kind of salad you'd make into a sandwich or eat with a main course; think tuna or potato salad.A dressed salad is a "normal" green salad served with some kind of salad dressing. These dressings (Ranch, Thousand Island, vinaigrettes) are usually made with mayonnaise or oil, but are used in a much lower quantity than in a bound salad.
That depends on the recipe you use.
Depends what else you put into it. I would make about 130 pounds of salad from 100 pounds potato as I add eggs, onion, bell peppers etc.
Generally speaking, 5 lbs of potato salad will fee 30 people. 12 people would be a little over half of that, so around 2.5 lbs of potato salad.
I would add more potatoes. or chuck it.

You should plan for about 1/2 cup per person. That make 250 cups which would be just under 16 gallons of potato salad.
