I don't see any way to get currency exchange rates to appear in the stocks module, but the FTSE100 appears to be listed under "LDN"
I found this for the EUR/USD rates: ERO

I assume you mean Chinese Yuan for CNY - http://investing.money.msn.com/investments/currency-exchange-rates/?symbol=%2fUSDCNY&FormatAs=Index, but I can't add this to the module.
I don't know what CHY/USD is.
The bottom line, though, seems to suggest that you will need to find an RSS feed for these indexes and exchange rates to add a custom module or modules as they don't appear to be valid for the current stock module on my.msn.com
