you can not eat an open can of anything that is not refridgerated. anything in a can must be consumed promptly or stored in a plastic container while in fridge. you can get sick if you leave it in the can.
Usually, no. Most kinds of olives are way too bitter to eat straight off the tree and must be cured in some sort of brine before they're fit for consumption. Now, I said usually, meaning that there's an exception. There is a kind of olive that can be eaten straight off the tree, but I can't remember what it's called.
Yes, but it wouldn't be very nice!
Yes. It takes a long time for bacteria to form on this product. It will spoil if left out of the refrigerator. It will dry out if left uncovered.
This can spoil if not kept in the refrigerator. Keep it in an airtight container to prevent drying out. It can last up to a week in the refrigerator.
Eventually bacteria will grow and cause it to spoil.
Nope. Once it is opened it needs to be put in your refrigerator, cooked or not.

It's good, but the Dr. Pepper will be flat when you drink it.
Most foods will eventually spoil when left in the open.
The question properly would be "How do apples spoil?" Eventually, they will turn brown or get brown spots on them if you leave them in the refrigerator too long... Try to use them before they begin getting brown spots. And frankly, you can still eat them and bake with them -- just cut away the brown spots. But I wouldn't ...
Meats are kept better in the freezer. Meats can be kept in the refrigerator for 3 to 4 days if raw and 1 to 2 days longer if cooked. Always place cooked meats in an airtight container.
Eventually, yes. It will also spoil if left inside the refrigerator, it just takes longer. Most vinaigrettes are made of nothing more than vinegar, oil and some herbs, all of which are shelf stable. The vinegar will never go bad, but herbs can loose their potency and oil will eventually go rancid. The onset of rancidity and the potency of the herbs can be maintained by keeping it refrigerated and the container sealed.
