Are my plants healthy?

Yeah looks like your doing ok to me man. Although when asking questions try do it with led lights off so you can get a better look at the plant. Dont worry to much about those little cotlyedons (2 very bottom leafs). I have had that a few times and it has never caused me any harm. Big pots for little plants so make sure you are just giving them a little drink and not to much. There is no need to water till run off or oversoak at this time.
