They all look fine to me.
I like bananas with a little bit of brown on them. I can't eat them raw, but I do like them. But, they don't seem to sell very well here.
I can also see some minor blemishes on the mangoes, and some bruises on the peaches. But, they would be fine for cooking/baking.
I'm guessing that the bell peppers are just getting a little soft or slightly wrinkled. Again, good for cooking.
