Answer 1

So that mean you can have multiple exception blocks
in a pl/sql script ?You can have one exception handler per execution block.
Execution blocks can be nested inside other execution blocks.
Handling the error within one exception handler causes execution to return out to the execution of the parent block.
Raising an error within one exception handler causes the execution to go straight to the exception handler of the parent block.
e.g.
-- execution block 1
BEGIN
  -- execution block 2
  DECLARE
    myvar number;
  BEGIN
    SELECT mynumber INTO myvar FROM mytable;
  EXCEPTION
    WHEN NO_DATA_FOUND THEN
      NULL;  -- handle error and return execution to block 1
    WHEN OTHERS THEN
      RAISE; -- raise any other errors to block 1 exception handler
  END; -- block 2
  DBMS_OUTPUT.PUT_LINE('Select took place successfully or no data was found');
EXCEPTION
  WHEN OTHERS THEN
    DBMS_OUTPUT.PUT_LINE('An error occurred either in block1 or in block 2 (except for NO_DATA_FOUND in block2)');
END;
