as far as i can tell, there is no bf dungeon5 key.
i found 6 keys, but i had two bf dungeon4 (i think) and no 5.
...so just realize that when you get bf dungeon6 you can complete both dungeons 5 and 6.
not really sure what you're asking in regard to the seeing stone and sword quests. i don't want to give too much away before i understand what you actually have (in inventory) and what you've tried.
...so, could you be a bit more speciific in your question(s) please (i just hate telling anyone what to do when all they need is a hint).
