When did you list these items?
If you are a new or returning seller, or when the site is busy, which it always is on a weekend, it can take up to 48 hours for items to appear in searches, though it is usually much sooner.
Even items listed at the same time, some may appear later, depending on how busy that category is.
If you revise the item, it will send it to the back of the queue again, too.
Items have to be indexed first, then join a queue with the others waiting to be listed.
As long as you can see the item in active listing, My eBay Selling, it is listed correctly, and it's just a waiting game for it to appear in searches.
