Your soil looks very wet and loose. The back 2 are fine as GG says.
Some dry soil on top as I see the white ends, they were beneath the soil, they just fell over cause your substrate is 2 loose. So press down lightly, nothing you can do about it been so wet.
But to avoid damping off after you press the soil down, (very very lightly now), then hold underneath the cotyledons (little leafs, if you don't have gloves make sure to wash your hands), hold her straight or in the direction you want her to grow and prop it up at least till you are covering the white that's been exposed by it falling over, and do not water as the roots will be down in the wet soil and keep the stem proped up with your new bit of dry soil.
Good luck
