It is not possible to attach to a neighbor's fence unless permission is given by the neighbor. It is a good idea to get any agreement in writing for attaching to the fence.
If the fence is yours - ie your boundary and on your land then the neighbor has no right to attach anything to it (without your permission).
Ask your neighbors if they care.
As long as the fence is on your property, no.
No. In fact no part of your neighbors roof or anything attached to that roof can even protrude over your fence. Most places have laws specifically stating how far away from your property line they have to keep their buildings.
Yes, if they own the fence.

I was raised to the fact that the owner of the fence is to mend the fence but good neighbors would often chip in with work or meterials
ask if he's ok with it, move the fence back, etc
The fence cannot be outside your property line.
You have no obligation, especially as they did not seek permission to attach. Simply detach theirs by any reasonable means and go your merry way. you should just have a discution with your next door neighbor and see why he\she stuck a nail threw your fence

If the plants are on your property they may be planted along your neighbors fence. However, climbing plants that will grow over the fence cannot be planted along your neighbors fence. Caveat: Make sure your neighbor has not installed the fence "inside" their property line so it lies a short distance FROM the property line. That is the practice in some areas and is required by the city ordinances in some areas. In that case, the land along the fence would belong to your neighbor. You need to determine where the property line is located and not assume the fence is on the property line.
