Assuming your Dropdown formfield's bookmark is 'Name', you could use a series of fields coded as:

{IF{REF Name}= "Joe" "Joe's Address¶
City, State Zip¶
Phone"}{IF{REF Name}= "Fred" "Fred's Address¶
City, State Zip¶
Phone"}{IF{REF Name}= "Mick" "Mick's Address¶
City, State Zip¶
Phone"}{IF{REF Name}= "Bill" "Bill's Address¶
City, State Zip¶
Phone"}

Note: The field brace pairs (ie '{ }') for the above examples are created in the body of the document via Ctrl-F9 (Cmd-F9 on a Mac) - you can't simply type them or copy & paste them from this message.
