Those are fairly low light plants, you won't need much fertilizer every two weeks maybe an underdose of Floruish by Seachem
, totally safe for fish. Just don't overdose, it'll cause an extreme spike in nitrite and nitrate. Since none of your plants are buried (unless your buried your anubias) you won't need root tabs.
Your plants are generally easy to care for, just roll the marimo moss ball everyday so all sides get some light. Once a week take it out from the tank, rinse it and squeeze it gently. I would suggest getting some lights for them, like hood lights, that'll make them thrive, something around 6500k fluorescent bulbs. Leave the lights on for 8 hours a day, they're low light plants. .
You won't neeed CO2 for them, CO2 are generally for carpeting plants.
