Oops, sorry I was in a hurry and didn`t see the photos
The first little leaves will be cotyledons - wait until some true leaves appear, and when the seedlings are easier to handle, loosen them up a bit in the tray with a plant label or something, and transplant them either to little pots, or if you haven`t got any pots into seen trays spaced out. You should get 30 - 40 in a tray.
Don`t touch the stems, but only hold the seedlings by the leaf. Put them in a sheltered place to grow on a bit and watch out for frost. At the moment all my seedlings ( a few thousand of them) are out on the back porch with a made up bubble wrap mini greenhouse/tent affair with a lump of fleece for overnight protection.
In May/June time, plant them out where you want them to flower - they should have a nice strong root by then and that`s it!
You will see your plants get stronger, and form lovely strong plants which are good and healthy. When they do flower they will look amazing and you will feel very proud of your efforts and post pictures on here for us all to look at .....won`t you
