Answer 1

In effect because you are wanting to take X rows and squish them down to 1 row per id, you are gouping on the ID to typically a group by clause is the best way to do this.
If you really wanted to do it without aggregate functions and a group by clause you would be looking for something like this...
SQL> ed
Wrote file afiedt.buf
  1  WITH t as (select 1 as id, '01-jan' as month, 10 as val from dual union all
  2             select 1, '01-feb', 20 from dual union all
  3             select 1, '01-mar', 30 from dual union all
  4             select 2, '01-jan', 10 from dual union all
  5             select 2, '01-feb', 30 from dual union all
  6             select 2, '01-mar', 60 from dual)

  8  select id, jan, feb, mar
  9  from (
10    select id
11          ,row_number() over (partition by id order by to_date(month,'dd-mon')) as rn
12          ,val as jan
13          ,lead(val) over (partition by id order by to_date(month,'dd-mon')) as feb
14          ,lead(val,2) over (partition by id order by to_date(month,'dd-mon')) as mar
15    from t
16    )
17* where rn = 1
SQL> /
        ID        JAN        FEB        MAR
         1         10         20         30
         2         10         30         60
SQL>Although this will only work if you can guarantee that there is a '01-jan' value for each id. If there could be missing values then you'll have to use aggregate functionality.
