Is it ok to run it on a mounted filesystem with concurrent read and write operations?
Yes. Please check man btrfs-balance. All such BTRFS operations are to be run on live, mounted filesystems. Performance will suffer and it might be long though.
Also, since the number of HDD is 5, how this "raid1" scheme is deployed?
BTRFS will manage storing 2 copies of every metadata block on 2 different disks, and will choose how by itself.
