Add all of the fruits together and toss with 1/2 cup sugar or 1/4 cup brown sugar and 1/4 cup of white sugar.
This will form a light coating of sweetness.
Adjust sugar level to your desired level of sweetness.
(I do use sugar replacement instead of sugar, so you might want to make two separate bowls of fruit for those guests/family who want the real sugar deal and one for those who are counting calories and carbs!)
If you are preparing this salad ahead of time, do not cut up the bananas and/or apples until just before serving to prevent them from discoloring.
Add bananas and apples at the very last minute.
