1. To estimate the schema sizes. Do this

SELECT a.ts#, a.name, b.bytes
FROM v$tablespace a, v$datafile b
WHERE a.ts# = b.ts#
AND upper(a.name) IN ('SYSTEM', 'TEMP', 'USERS', 'UNDO');

2. Controlfiles I don't know. You might need to check the os file size.

3. For log file size. Select * from v$log or select sum(bytes) from v$log;
