Name Que item

My multiple queue items don't seem to run in order or wait for the previously queue items to finish before the next one runs. So, queue item 1 downloads from remote, queue item 2 copied that and put it in another folder. Queue item 2 runs at the same time or not correctly  even though the Guarantee serialized execution is checked. Can I have the queue items run in order, waiting for the other to finish and is there a way to rename the queue items to make them distinctive?
