The only way I can give you a simple answer is to let you know how many different denominations exist. For many of these stamps, there are numerous paper/perforation/overprint varieties. You will need to directly consult a catalog if you want those details.
I will do that for the first few pics to let you have an idea. The remaining pics come from several different sets and is just too much for me to itemize for you, sorry.
Pic 1-2: 19 denominations
Pic 3:
R1 -- S1,4-5 Emperor Karl I: 20 denominations
R1 -- S2 Emperor Franz Josef with KUK FELDPOST ovpt: 21 denominations
R1 -- S3 Emperor Franz Josef with no overprint: 25 denominations (not including 2 color varieties -- 27 stamps in set), 1K and higher denominations are a different design but included in the counts)
R2 -- S1-4: 4 denominations (check for the numerous perf varieties)
R2 -- S5 (stamps inscribed "MILITARPOST" are listed under Bosnia & Herzegovina in the Scott catalog): 3 denominations (the 15h stamp will show Empress Zita)
Hope the above will give you a rough idea. If you really want to complete those sets, you really need to get hold of the Scott catalog.
