I tried to group based on groupID and created a case where groupId count equals or is higher as 1 and the eligibility is Yes.

Answer 1

Your question is a bit unclear due to lack of information about constraints, all the values in table etc.
With the given information tho, your task might be done by following query:
with groupData as
(
Select groupid,payable from put_your_table_name_here
where payable is not null
group by groupid
)
Select pt.id
,pt.groupId
,gd.payable
,pt.result
from put_your_table_name_here pt
left join groupData gd on gd.groupid=pt.groupid
The query has it drawbacks- you should give some more info about constraints, but generally it should work.
If you wouldnt want to have null values in payable column, you could change left join to join.

Answer 2

WITH CTE(ID, GroupID, Payable)AS
(
SELECT 111,'A','YES'
UNION ALL
SELECT 222,'A',''
UNION ALL
SELECT 333,'A',''
UNION ALL
SELECT 444,'B',''
UNION ALL
SELECT 555,'B','YES'
UNION ALL
SELECT 777,'B',''
UNION ALL
SELECT 888,'C',''
)
SELECT C.ID,C.GroupID,C.Payable,F.FLAG
FROM CTE AS C
JOIN
(
SELECT X.GROUPID,MAX(PAYABLE)FLAG
FROM CTE AS X
GROUP BY X.GroupID
)F ON C.GroupID=F.GroupID
ORDER BY C.ID;
You can try something like this
or
SELECT C.ID,C.GroupID,C.Payable,
FIRST_VALUE(C.PAYABLE)OVER(PARTITION BY C.GROUPID ORDER BY C.PAYABLE DESC)XCOL
FROM CTE AS C
ORDER BY C.ID;

Answer 3

with data (ID,GroupID,Payable) as (
Select 111, 'a', 'Yes' from dual union all
Select 222, 'a', null from dual union all
Select 333, 'a', null from dual union all
Select 444, 'b', null from dual union all
Select 555, 'b', 'Yes' from dual union all
Select 777, 'b', null from dual union all
Select 888, 'c', null from dual
)
,result as(
select GroupID, case when Count(*) > 1 then 'Yes' else null end Result
from data
group by GroupID)
Select * from data
Join result on data.GroupID = result.GroupID
order by data.ID,data.GroupID
