Thank you all, but irrespective of count i have why is it keeping old files?

Because you're telling it to!!

max_wal_size= 1GB
wal_keep_segments=500

and how is it using those files? Is there any processes that can flush or remove those files?

Change the parameter and restart the server...

They are in a subdir (under /opt/pgdata), and the OP seems likely to
have omitted the self/parent hidden directories during his check as
well.  Plus per the docs we actually expect 501 so there isn't a need
to account for 6 extra, just 5.
