Answer 1

If you have not backed up the table (for example, by using RMAN, EXPDP or EXP) or created a RESTORE POINT then your data is lost.
From the Oracle documentation:
Caution:
You cannot roll back a TRUNCATE TABLE statement, nor can you use a FLASHBACK TABLE statement to retrieve the contents of a table that has been truncated.
You can check if you have an RMAN backup by logging into RMAN (rather than into the database) and using the LIST command.
You can check if you have a restore point (from a database user with the appropriate permissions) using:
SELECT name,
guarantee_flashback_database,
pdb_restore_point,
clean_pdb_restore_point,
pdb_incarnation#,
storage_size
FROM v$restore_point;
You are looking for a restore point where guarantee_flashback_database is YES.
(Assuming that the RESTORE POINT was created after the table was created and populated.)
Note:
If you restore from a backup or to a restore point then all changes made since that backup or creating the restore point will be lost.
