Any idea what these are? I'm guessing giant replica, but on the outside chance they are something desirable thought you guys would know. Also wondering about the other coin(s), not sure about the similar pair, again may not even be a coin. The one piece is for certain a coin, not sure where from though. Thanks for having a look!

1st top pic coin on far left looks like China I found several coins that look like it in my 19th century world coins Krause book 1801-1900 prices range from $200-2,000. not sure if yours is real or fake ? worth checking out for sure.
1st top pic coin in the lower middle looks like Japan. Japan C#7 , denomination-100 Mon (Tempo Tsuho) metal-cast Bronze Date-ND(1835-70) date/value VG-$5.00 F-$8.00 VF-$12.00 XF-$17.50 not sure what grade your coin is ?
1st pic top right coin. I am going to take a guess at it being from Korea ? the reason I am guess this country is because of the square hole in the middle being bigger than Chinese coins and the large square hole looks like some 19th century Korean coins. ???
The top three are all fakes. Your scans aren't really good enough to evaluate the Tibetan pieces but, considering the company they keep, I doubt they are authentic.
