So I guess my answer is, just go for it! Give those transplants some compost tea when you transplant, and they'll probably do just fine! I don't think they need the soil you planted them in to survive...

Yes lol maybe pluck was too strong a word lol
You should have plenty of luck. If they all die you've done something wrong
But, as others have been saying, if you pop out the plug of medium from the tray and carefully tease it apart so your tiny seedlings are separated from one another but keeping as much of the medium as possible with the roots of each seedling and plant those, you are much more likely to have success with your transplants.
Personally, I would be inclined to ignore the spacing requirements on the package and go ahead and plant each plug, with its multiple seedlings. Space the plugs according to the recommendations on the package, and let the seedlings sort it out amongst themselves as to which will and which will not make it.
I do all of my seed starts in wooden flats in a mix of leaf mold, compost and this year perlite instead of sand. I find having the soil somewhat dry...not soggy...helps to separate the roots for transplant...I use a kitchen fork to work a section of them up and then gently pull apart. if they are too wet they are heavy and the roots stick together more. Then I pot into soil that is already soaked....same in the garden, I tend to prewater the hole besides watering after setting the plant.
Sorry about the big pictures, I haven't understood how to make them smaller.
