Will this plan work for a one gallon and a (maybe) half gallon jug? (In description)

So I’m planning on making the 1 gallon into an aquarium with wild hornwort I’ll find, leftover java moss, and maybe some other plants. Could I use regular dirt form outside capped with sand? And could snails live in it maybe? For the half gallon I was thinking just a small terrarium with moss. Could anything live in here? And what other plants could easily grow in the half gallon?
