Hi Cindy,
I tend to list whenever I can get a listing ready. I've noticed that there is someone always shopping no matter what time of day or night, so it doesn't seem to matter what time you list.
But I wouldn't list all 5 drafts at the same time. I would definitely stagger them. I have noticed that my views, sales, etc. increase when I'm "working" in my shop. In other words, spread out the time between your listings and do some tweeking to expiring listings, rearrange your shop, etc. a little bit each day so it looks like you are actively working.
Hope this helps.
