Limit the number of results from a querying a table

Question

I have a table, NAMES, that holds appx 50 names.
I want to be able to list a certain amount of names and once that limit is reached( 6 or 7 or so), output a row / link / statement that says, you've reached your limit.
For example the output would look similar to :
Jim
John
James
Mike
Henry
Mark
'Limit Reached'
'Limit Reached' would eventually need to be a link, but I am already familiar with creating links from query results, persay.
I've experimented with listagg, case statements and decode but am not sure how to do this. I'm thinking decode is the way to go but am not sure how to keep track of a counter as the sql is running. This needs to be written in sql only, not pl/sql, if possible. My query so far is
Select first, last
From Names
where rownum <= 6
Not sure how to accomplish this. Any help would be greatly appreciated. Thanks in advance

I have tested these using union. However, I also have columns I need to include that aren't text fields (such as an ID column, which is a number / integer type). I can't use NULL. Is there anything to substitue for this?
Other people can use NULL.  Why can't you?
If you could use NULL. then you could do something like this:
SELECT  ename
,       job
,       sal     -- a NUMBER column
FROM    scott.emp
WHERE   ROWNUM  <= 6
    UNION ALL
SELECT  'Limit reached'
,       NULL    -- in place of a VARCHAR2
,       NULL    -- in place of a NUMBER
FROM    dual
Output:
ENAME         JOB              SAL
SMITH         CLERK            800
ALLEN         SALESMAN        1600
WARD          SALESMAN        1250
JONES         MANAGER         2975
MARTIN        SALESMAN        1250
BLAKE         MANAGER         2850
Limit reached
