Add pineapple, oranges and apples to a medium bowl. Pour lemon juice over fruit and toss to coat. (This will help prevent the apples from turning brown.)
Add the cherries and banana. Gently toss. Stir in greek yogurt, vanilla and cool whip.
Stir in marshmallows and coconut last. Gently toss to combine everything. Cover bowl and place in fridge to let chill for at least 3 hours before serving. Enjoy!
