CONTEXT parameters can be used from inside the VM for initializing the image during startup. 

> 1) does the hostname refer to "host-1"?

No. The $NAME refers to the name of the initialized VM. In your example this is "ttylinux". 
You can define whatever you want, e.g. based on the $VMID parameter. 

> 2) what should the ip_public be?

What do you mean with "should"? 

> 3) what should the username be?

Typically, it would be the user that initialized the VM. --> $USER[NAME] 
> Please let me know if anything unclear.
