Convert multiple date varchar2 to date format in Oracle 11g

wish helps you I'd suggest using a case statement with regexp_like conditions to detect likely formats and return dates using the appropriate date mask in the then clauses e.g.:
code :
with tz as (
SELECT distinct tzabbrev
     , first_value(min(tzname)) over (partition by tzabbrev order by count(*) desc) tzname
  FROM v$timezone_names 
 group by tzabbrev
     , TZ_OFFSET(tzname)
), dta as (
select yt.install_date
     , regexp_replace(yt.install_date,tzabbrev,tzname,1,1,'i') install_date2
  from your_table yt
  left join tz
    on regexp_like(install_date, tz.TZABBREV,'i')
)
select install_date, install_date2
     , to_timestamp_tz( install_date2
              , case 
                  when regexp_like(install_date2,'^[A-Z]{3,} [A-Z]{3,} [0-9]{1,2} [0-9]{1,2}(:[0-9]{2}){1,2} [[:print:]]{5,} [0-9]{2,4}','i') then 'DY MON DD HH24:MI:SS TZR YYYY'
                  when regexp_like(install_date2,'^[A-Z]{4,},? [A-Z]{3,},? [0-9]{1,2},? [0-9]{2,4}','i') then 'DAY MONTH DD YYYY'
                  when regexp_like(install_date2,'^[A-Z]{3},? [A-Z]{3,},? [0-9]{1,2},? [0-9]{2,4}','i') then 'DY MONTH DD YYYY'
                  when regexp_like(install_date2,'^[0-9]{1,2}[-/][0-9]{1,2}[-/]([0-9]{2}){1,2}') then 'MM-DD-RRRR'
                  when regexp_like(install_date2,'^[0-9]{1,2}[-/ ][A-Z]{3,}[-/ ]([0-9]{2}){1,2}','i') then 'DD-MON-RRRR'
                  when regexp_like(install_date2,'^[A-Z]{3,}[-/ ][0-9]{1,2},?[-/ ]([0-9]{2}){1,2}','i') then 'MON-DD-RRRR'
                  when regexp_like(install_date2,'^(19|20)[0-9]{6}') then 'RRRRMMDD'
                  when regexp_like(install_date2,'^[23][0-9]{5}') then 'DDMMRR'
                  when regexp_like(install_date2,'^[0-9]{6}') then 'MMDDRR'
                  when regexp_like(install_date2,'^[01][0-9]{7}') then 'MMDDRRRR'
                  when regexp_like(install_date2,'^[23][0-9]{7}') then 'DDMMRRRR'
                  ELSE NULL
                end
              ||case
                  when regexp_like(install_date2, '[0-9]{1,2}(:[0-9]{2}){1,2}$') then ' HH24:MI:SS'
                  when regexp_like(install_date2, '[0-9]{1,2}(:[0-9]{2}){1,2} ?(am|pm)$','i') then ' HH:MI:SS AM'
                  else null
