Consider below query

with sample_data as (
  select '05-May-2021 17:03:58' Create_Date union all
  select '19-10-2020 10:16:26' union all
  select '09/10/2019' union all
  select '28-03-2020 10:16:26' union all
  select '05-June-2020 16:23:17' union all
  select '20/12/2020'
)
select from_unixtime(coalesce(
         unix_timestamp(Create_Date, 'dd-MMM-yyyy HH:mm:ss'),
         unix_timestamp(Create_Date, 'dd-MM-yyyy HH:mm:ss'),
         unix_timestamp(Create_Date, 'dd/MM/yyyy')
       ), 'YYYY-MM-dd') Create_Date
  from sample_data;
