>>While donig database installation I'm getting different free space.
Did you run this query against the ASM instance or Database?
You are supposed to do it in ASM instance.
set your ORACLE_SID to +ASM and try.
Also crosscheck the output with
 asmcmd lsdg

Unless this is for learning purposes, you must be using external redundancy.
It is also to be noted that there are several bugs related to this.

Yes. I have only one asm instance.
