Hi pcm2007 or should I say 'Hola!"

Hello friends,
I need to identify these other coins:

1.-



2.-



3.-

1) Ethiopia, one of the Haile Selassie types of 1944. Not sure what the denomination is; there's a difference in size (which I don't know) and a slight difference in lettering (which I can't read).

2) Pakistan, 1 rupee 2006.

3) Austrian Empire, 4 kreuzer 1861-A.

4) Copy of an early medieval portrait denier of Charles (don't know enough to say which Charles, or the origin of the copy).

5) Brazil, ca. 1823-32, 80 reis, counterstamped with new value 40 reis in 1835. Can't find the undertype date, unfortunately.

No idea on number 6, can't see any 1656 anywhere.
6) Austrian Empire, 1 kreuzer. Not sure on the date, but looks like 1858 (one of the commonest dates for the type). Can't see the mintmark at all.
