Yes, you will need to post some bloom and foliage photos for help. With number 2 and 7 you might try googling the code and seeing if the person who sells these has the actual name of the plant or of the parents of the plant. I have not tried, but that would be my first guess. The ones with names could probably be looked up on the RHS website. There are a few very good links in our LINKS thread. Check them out and hopefully you will find some answers. See Number 4 & 28 specifically.
