Yes, with the use of Navigator and various development tools such as  
WDSc and RDI. There are still some things that can only be done from a  
green-screen and there are a few things that can only be done from the  
Navigator interface (in one of its many incarnations e.g., Windows  
client, Nav for Web, etc.) or via APIs.

Yes. Very similar data stream except that 5250 could be considered a  
superset of 3270.

Depends. Often still 5250 but may be client/server or browser-based.

Nope. CICS/400 does exist and is used by z/OS shops converting to i.  
Rarely (if ever) used by pure i/OS shops. Externally described display  
files (via DDS, multiple record formats, subfiles etc.) are far easier  
to use than CICS.
