How can I make separate partition (to install windows 7) using ubuntu.

That key icon indicates that the partition you are trying to modify is currently under use. In order to modify that/those partition/s you have to boot up from a live CD. Then you will be able to modify those partitions. But, be sure to backup your data as it can lead to data loss. But this case is very rare.
