Sorry,I havn't logged in for some time.
All four are OK.
The first (Kassel) is fairly common, and only books at 15 Euro.
The second is a Winterhifswerk donation badge, (possibly Tag der Wehrmacht) hard to find in good condition as they all seem to suffer from some degree of zinc pest, I don't have the reference books on these, but it is also fairly common.
The third is very very common, about 10 Euro, it also is prone to the pest and loss of finish.
As noted above the HJ tinnie is the best of the bunch and books at 35 Euro, but mad keen HJ collectors may go more, its the only one I do not have. Note that there is no location (town etc.) on this one, but it should be possible to find out using the Bann? number.
Regards,
Pete
