For your latest group picture, and counting from top left, you've got:
Line 1:
Coins 1 to 6: German 2 pfennigs and 5 pfennigs. Scoutjim outlined the periods, but that's a good cross-section of German historical periods you've got there. I can't tell if coin number 3's colour is natural, but from what I can see it seems in pretty good condition.
Coin 7: Mexico 5 centavos.
Coin 8: USSR 2 kopeks.
Line 2:
Coin 9: Japan 10 yen. These are tricky to date; you'd need to familiarize yourself with the Sino-Japanese numeral system.
Coin 10: USSR 3 kopeks.
Coins 11 and 12: Israel 5 sheqalim, 1990's period. Another country with hard-to-date coins; you basically need the "how to convert Hebrew dates" guide from the Krause catalogue. The first (with the portrait) is a one-year--only commemorative from 1990; the second is the "normal" design, issued from 1990 to today.
Coins 13 and 15: West African States 10 and 25 francs.
Coin 14: French West Africa 10 francs - same place as the other two, just a different name (from the colonial, pre-independence period).
Line 3:
Coin 16: Canada 1 cent.
Coin 17: Nazi Germany zinc 2 pfennig.
Coin 18: No idea. It's a bit flat

. Does that say "1 kreuzer"? It might be a German States coin, or perhaps Austrian.
Coin 19: West Germany 10 pfennig. It's supposed to be brass-clad steel, but someone's taken the brass away!
Coin 20: Philippines (U.S. colony) 1 centavo.
Coins 21 and 22: Panama 5 centavos and 1 decimo.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
