Hi Janome.
I would try to use one of the websites such as those QuizmasterG suggetsed in post #14.
For example if you ...
(1) go to www.everyhit.com
(2) select "Order research results by Alphabetical-title"
(3) type 'N' and 'J' into the first two search boxes
(4) hit the search button
... a short list of possible matches is displayed with a direct hit for your no.5 ("JS by N") at the top of the list (a hit in Dec 2005).
Maybe the other answers will fall as easily also (I don't know)? Happy to try to help with any that aren't so easily cracked.
