Paperclip - Might take a while.
Penny - Not sure what American coins are made of but most likely this is an alloy of more than one metal, making it harder to corrode
Steel spoon - Presuming that you mean stainless steel...it won't rust, since it's made for the elements, and it's an alloy of many different metals.
Small ball of aluminum foil - Won't rust. Aluminum has a protective oxide coating that acts as a shield to prevent the actual aluminum from corroding

Can a paperclip rust in a day? Probably. Just make a small nick/scratch in the paper clip and it will rust faster.
Penny? I'm not sure. Probably awhile.
Steel spoons are usually plated with another metal; so if you remove that metal coating, it will probably rust just as fast as a paperclip (if a paperclip were the size of the spoon)
Al foil... Aluminum will not rust very far; Aluminum becomes aluminum oxide -- see rubies/sapphires. This coating protects the aluminum so it will not rust beyond a very thin coating of aluminum oxide. However, if you add a little bit of liquid mercury, it will rust.
