Ok. Open iTunes on your iPhone/iPod/iPad, select purchased, then hit the tab that says "not on this iPhone. Your purchased items shoud show up with a little cloud next them. Tap the clouds and it will download the content to the music app of that device.
Looks like those songs are already on your device. So no reason for it to show a cloud. Here's a pic of one of my albums not on my iPad, but in the cloud.
Delete one of them from your phone, then go back to iTunes/Purchased/Not on this phone. That song you deleted from your phone should show up there with a litte cloud icon next to it. Not sure how long it takes iTunes to see the delete from phone, then cue the deleted song for download though. So you might want to give it a few minutes after you delete it from your phone.
