Caffeine occurs naturally in a number of plants. The most well-known of these are tea, coffee, and the cocoa plant. Coffee and tea contain more caffeine than the cocoa plant, which just contains small amounts. There are other plants, however, which naturally contain caffeine. These include yerba mate, guayusa, and yaupon, which are all species of holly. A few other species of holly also contain some caffeine. Another unrelated plant (related to maple trees actually), called guarana, contains caffeine. There may be others but these are the only plants that I know of that contain caffeine.
One nut that contains caffeine is the Kola nut, which is used to make chocolate.

Wine doesn't have caffeine in it. Coffee, tea and chocolate, especially dark chocolate, all have caffeine in them to varying degrees. Many energy drinks, and caffeine pills too, also have caffeine in them, often in high doses. The amount of caffeine in each of these consumables varies, generally coffee has the most, followed by tea, with chocolate having the least amount of caffeine.

No. Not even a little bit. Apples, as a pomaceous fruit, do not naturally contain caffeine. They do, however, have about 19 grams of sugar for one average medium - natural sugar, which is much healthier than the 4 grams of Sweet 'N Low mixed into your daily coffee. So despite the high sugar levels, eating an apple is a much healthier alternative to drinking coffee. The sugars are also one of the main reasons apples have similar effects to caffeine.
