Potato salad should not be left unrefrigerated for more than two hours. Less time is better. In fact, if the ambient temperature is around 90°F, cut that time to less than 1 hour.
This information should be on the potato salad packaging. I would use within a day or two of opening.
On a hot day not very long. Needs to be kept cool and on ice because of the mayonnaise involved. Couple of hours at the most.
About 5-7 days if stored properly.

Chicken salad can last in the refrigerator for three to five days after it is prepared. It is not recommended this food be frozen.
Potato salad will never be as good as when it was first made. Use it within a day or two. Depending on what you put in your potato salad will depend on how long your salad will last. If you put eggs in your salad then you have 3 days to use it up in. If you omit the eggs then you have about 5 days as long as the salad doesn't sit out and get warm since it has mayonnaise in it.
If tightly covered, 3-4 days.
Many people save the pickle juice after the pickles are gone. I use it to flavor potato salad, deviled eggs, tuna salad...use your imagination. It adds a delicious flavor to many dishes. I store the pickle juice in the fridge for months and have never had it to go bad.
2-3 days
