Without performing lab tests, there's no way to know.
If it has been handled and refrigerated properly, looks and smells good, and is properly and thoroughly reheated, it will probably be OK. You are the one who has to make the decision of whether or not to use it.

If it has been frozen, yes.
It depends on numerous things. The most important part is how was it handled? All refrigerated processed meats should be kept refrigerated between 32°F and 39°F. If your ham was handled in an ideal/perfect conditions and is in code date, it should be consumed with in seven days, five is better.
The bone itself can not spoil but the marrow inside the bone will spoil. Keep the bone refrigerated until you use it. Any meat on the bone could also spoil.
no - it isn't safe to use on sandwiches either i recommend you throw it away and get another pack
There are no "safe" days to have sex. Use birth control.
Technically yes, although you are taking a large risk of becoming ill from bacteria on the ham. The "use by" dates on raw meat products are for safety reasons - after this, the producer cannot reasonably guarantee the product is safe.
No, its use now a days is to symbolize a poison.
A smoked ham hock should keep refrigerated for up to a week, though I have had some become moldy before that. I try to use mine within a couple days of purchase.
Usually there is a date on the ham for how long you can keep it. Many times I find cured hams have a refrigeration life of a month or two. After you open it, it should be good for 3+ days. Whatever you cannot eat within a couple of days, should be stored in the freezer with proper packaging. I find cutting it all up and putting it in multiple packages so I don't take out any more than I need at a time. I use the ham bone and scraps for soup, such as lentil, split pea and/or bean soup for a great change of pace.
The fastest and most safe way to thaw a frozen ham is to place it in cold water, changing the water every 30 minutes until thawed.
No it is not! By now it has either freezer burn or has gone bad! That could definitely make you sick! :)
