Answer 1

You'll need to cross join a set of three rows to your base table.
There are different ways to do it, for example :
SQL> select name1 ||
  2         case n when 1 then ' is a planet'
  3                when 2 then ' is almost round'
  4                when 3 then ' revolves around the sun'
  5         end as final_name
  6  from test1
  7       cross join (
  8         select level n
  9         from dual
10         connect by level <= 3
11       )
12  order by 1
13  ;
FINAL_NAME
EARTH is a planet
EARTH is almost round
EARTH revolves around the sun
JUPITER is a planet
JUPITER is almost round
JUPITER revolves around the sun
MARS is a planet
MARS is almost round
MARS revolves around the sun
VENUS is a planet
VENUS is almost round
VENUS revolves around the sun
12 rows selected
SQL> select name1 || text as final_name
  2  from (
  3    select name1
  4         , ' is a planet' as text1
  5         , ' is almost round' as text2
  6         , ' revolves around the sun' as text3
  7    from test1
  8  )
  9  unpivot (text for text# in (text1, text2, text3))
10  ;
