Coin collectors...I need some help!!!

Started sorting through some old coins in my collection. In desperate need of some money and was looking to sell a few. But...I have no idea what some of them are. Most were givin to me by my grandpa who did some traveling. Most are from Asia or Europe. Have a ton of German coins. Heres the main 6 in question.
1,2,3
4,5,6
Fronts

Backs

Scans came out kind of dark.
#1 Edit: Solved...100 Cash coin from Ho-Nan China.
#2 couldnt get to come out any lighter...its in pretty good condition. Date is 1856, front lettering is "NAPOLEON III EMPEREUR"...back lettering "EMPIRE FRANCAIS DIX CENTIMES" Diameter is 1 1/8 inch.
#3 only english lettering is on the front..."10 SEN" the rest is in an Asian language. 5/8ths inch diameter.
#4 Date 1936, front lettering "ESTADOS UNIDOS MEXICANO" back lettering "1936 M 5 CENTAVOS" 3/4 inch diameter.
#5 front lettering "HALF DRACHM OSCO" Under the 3 S theres a tiny U.S.A. printed. Back is the same minus the USA. Smallest coin I own with only a 9/16 inch diameter.
#6 Front lettering "LIBERTE EGALITE FRATERNITE" 5 hole C with "MES" printed in the middle, 1920. Back just has the R hole F.
Any information on these coins would be appriciated. Have more in question but these are the ons I think would have the most value.
