Answer 1: Following is the flow trace when an exception hasn't been
serviced in its original try/catch block and continue at the next catch
block.

i. Finally of original try/catch
(Optional) Finally of other try/catch blocks (up the stack) where
exception was not serviced
ii. Catch block where exception was serviced.
iii. Finally of the catch where exception was serviced.

Answer 2: Try/catch can not be looped unless you use labels (see: goto
statement). I personally think that it is not a good idea to loop a
try/catch. because if a statement fails once, it'll always fail to pass
try/catch.

I don't have much Idea about your third question.
HTH. Cheers :)
