Hello,
Indeed difficult. And the book for those is not easily available (CNA I,

Koch).
You can look in Ruckser available here
http://www.numismatas.com/Forum/Pdf/David%20Ruckser/Coins%20of%20Austria.pdf. It is the first easiest step.
There are a few in our catalogue under Austria Habsburg, Austrian states (Carinthia, Styria, Salzburg) but so few that it only gives a slight idea.
#2 is Wiener, maybe Wiener Neustadt. You turn it clockwise 135° and get the "binden shield". But I can't tell more. It looks like having angel wings around the shield.
Your #4 is similar to

If you can provide slightly sharper pics, and once we manage to identify, I'll add them with pleasure to our catalogue

. #1 will be a first great addition !
Regards.
