Does anyone know if there is a protocol defined limit to the number of devices in a group?  I hear it’s 5, but I haven’t found any documentation on this.

Depends on the device mfg. Some only allow 4. 

Also know that devices activated via association will not update their status in the Isy

As an Insteon user, this limit sounds really low. It sounds odd you can’t group more than 5 switches together.  
 

Do you know if you can “chain” devices? 
 

If you have two groups:

ABCX

XYZ

And you press Z, will that fire off ABC?

No, that's not possible. It is low and not odds. There's pros and cons to both protocols. This is one of zwave's cons and one of the many reasons why I wouldn't use zwave for lighting
