So, let me try to understand this. You don't have a single DB backup but you want to restore?

Not in another group, in the same group.
The idea is if one member of the group is corrupted another may not.
Please post the result of the queries I provided.
Please post the abstract of alert.log showing the corruption.
What is the current state of your database/instance?

Regards
Michel

So you have only one member per group. It does not seem there is any problem.
What is in your alert.log file?
Post what you can see if you "alter database open;".

Please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code, use code tags and align the columns in result.
Use the "Preview Message" button to verify.

Regards
Michel

In mount state, execute:
alter database clear logfile 'D:\APP\ORACLE\ORADATA\ORCL\REDO01.LOG';
and try to open teh database.
Tell us what happens, depending on the cases the solution is different.

Michel
