I do not know where these coins are, what year are they from, and what denomination they have (exept fot the Ni one). Could you please help me ? Thanks!
The nickel 20 para is dated year 9 of Muhammad V's reign which is roughly equivalent to 1915AD. The brass 20 para is a circa 1913 token for passage over the Galata Bridge which links the two parts of Istanbul. A similar one and the info about them can be seen about 2/3 down this page: http://home.psknet.com/tbirde3/Medals/Medals.html
