Answer 1

You can get the array values using JSON_TABLE and then aggregate using LISTAGG :

SELECT LISTAGG( orgPhoneNum, ',' ) WITHIN GROUP ( ORDER BY row_number )
         AS orgPhoneNums
FROM   JSON_TABLE(
         '{"orgPhoneNum":[["9952044727"],["5464646464"]]}',
         '$.orgPhoneNum[*][*]'
         COLUMNS (
           row_number FOR ORDINALITY,
           orgPhoneNum VARCHAR2(10) PATH '$'
         )
       )

Which outputs:

 |  ORGPHONENUMS | |:-------------------- |  |  9952044727,5464646464 |
