Well the piercings will not close up completely after that period of time. It can take a year or longer for piercings over a year old to shrink and close.
Well just about as long as you have had them plus 3 months. See if the piercings are over a year old they wont close the will shrink but the piercings will take months to shrink down to a point where they are no longer visible.
It depends on how fast your body heals, and how long you have had the piercing. The longer you have had the piercing, the longer it will take to close. This is true for all piercings.
Mouth piercings are likely to close almost instantly once you take them out, no matter how long you have had them.
It depends on your age, how long you had them, where the earrings are, and how thick they were. They're more likely to close or close faster if you're younger, didn't wear earrings for that long, if you're talking about piercings other than plain simple lobe piercings, and if the earrings were thin. Regular ear lobe piercings may never close.
This depends on how long the piercings had jewellery in them, the longer the jewellery has been left in the piercings the longer the piercings will take to shrink and eventually close, months to years it all depends on time.
Some people's bodies are different when it comes to the healing process. Take out your piercing and just wait. It may take from a couple months to a year to close. Everyone's body is different.
There's no way to be sure honestly. Some people can have piercings for years that never fully heal to the point that they don't close. If you have other piercings that have healed to that point, you can use that as a gauge but otherwise, don't remove the jewelry unless you want to risk losing the piercing :)
Dimple piercings can start to close within a few hours to a few days if left without jewelry. However, full closure may take a few weeks to months, depending on the individual's healing rate and how long the piercings have been in place.

Depends on your body. Usually for piercings that old, theres very little chance that it will close up. If you want them to close, you can try massaging them with jojoba or vitamin E oil. If you dont wan them to close, but need to take them out for work or something, try clear retainers.
If you intend on keeping the piercings, jewellery should be left in the piercings, there is no reason to remove the jewellery except to get rid of the piercings. Piercings can take a full year to become seasoned to the point where jewellery can be removed for extended periods.
