Please Help With Identify These Chinese Coins Or Tokens ?

Lower left (and upside down) appears to be similar to a 1 Cash Kangxi, 1662-1722. They are typically 25mm to 28mm in dia. This may be a modern reproduction. Originals had characters on the reverse indicating mint.
Others unknown.

Hello Chute72 and Publius

Thanks for your reply's.

The photo above shows three different items actually ( two are the same ).
The bottom right coin is actually the obverse of the coin on the bottom left.
Both coins on the bottom measure 38-mm in diameter and they are very light weight.
I do not own a device to weight coins.
What type or brand of weighting machine might you recommend ?

The fantasy coin on the upper left is magnetic, although it looks silver.
The other three items are not magnetic and look brass.
What type of testing kit would I buy to help determine silver content ?
Can you give me a link or book title which best describes the various metals in coins and how to determine what each metal is.

The large amulet ( upper right) looks like it might have been used as some type of a Netsuke or Ojime ( just a guess ). The two very small holes ( at top and bottom ) are roughly drilled with metal still remaining. And the amulet is a bit concaved in the center.
