Answer 1

with COUNT_TEST(NAME, ID) as(
 select 'A',4 from DUAL union all
 select 'B',3 from DUAL union all
 select 'C',2 from DUAL union all
 select 'D',1 from DUAL
)
  select NAME, ID
    from COUNT_TEST
 connect by NAME=prior NAME and level<=ID
     and prior DBMS_RANDOM.value is not null;

Here is a Rextester for it.
