This claim has already been featured on snopes.com and was rated "mixture of true and false information":
However, the best that can be said at this point is that citrus fruits may potentially harbor anti-cancer properties that could help ward off cancer. No reputable scientific or medical studies have reported that lemons have been found to be a "proven ...

Regarding the nutrients, you're better off in general consuming the whole fruit, not just the juice. I'll look at oranges and apples. You can use the links and do the math to figure the same thing out for the other items, I imagine.
Orange vs Orange Juice
One medium orange (about 130g) contains 1.2g protein, 3.1g fiber, 116% daily value (DV) of Vitamin C, ...

Ethylene definitely has a role in the ripening of fruit.
Ethylene and fruit ripening is a scientific paper that discusses the chemical mechanisms of ripening fruit. From the paper:
The ripening of fleshy fruits corresponds to a series of biochemical, physiological and structural changes that make the fruit attractive to the consumer. Although these ...

Maybe.
D-limonene is one of the most common terpenes in nature. It is a major
constituent in several citrus oils (orange, lemon, mandarin, lime, and
grapefruit).
D-limonene has well-established chemopreventive activity against many
types of cancer. Evidence from a phase I clinical trial demonstrated a
partial response in a patient with breast ...

Yes.
Temperate Fruit Crops in Warm Climates at page 178:
A general objective in most breeding programs is higher sugar content
See Survey of Food and Nutrition Research in the United States, which lists a publication titled:
Fruit breeding. Improvement in color, flavor, sugar content, and yield of apricots, plums, peaches, nectarines, sweet cherries, ...

The intended meaning of the quote you supplied is surely that if the outside of layer of a fruit or vegetable is commonly consumed then this would be taken in to account when setting a maximum residue level (MRL).
Zest of lemon and orange is commonly consumed and therefore those fruits must reasonably be included in the Food Standards Agency's claims about ...

Broadly yes,
You lose most of the fibre present in the fruit, fibre is important for digestion and likely has other benefits (http://www.nhs.uk/chq/pages/1141.aspx?categoryid=51), it also helps slow the absorption of the sugar in the fruit as the gut cannot digest fibre.
The vitamin/mineral compositions also change in processing and storage, the process of ...

The condition is called Benign Fasciculation Syndrome. No direct study of bananas (or any other food) as a treatment for BFS has ever been done, as far as I can find with Google scholar, but we can find some evidence in pieces.
The direct cause of BFS is not currently known, but there is evidence that it is induced by magnesium deficiency. The publication ...

It appears that this is an area of dispute amongst the experts, and I don't believe the research supports any bold claims.
For example, in 2016 Mother Jones interviewed Robert Lustig, who has been the subject of many Skeptics.SE questions here, and who provided limited evidence to the journalist.
Then the journalist followed up with David Katz, director ...

In re
[Sklivvz:] Guys, I'm challenging a widely repeated claim and provide a few examples. A scientific study of the ripening effects of apples or bananas is enough to answer it. I really really don't care about hearing that ethylene is ripening. It's not relevant at all. Show me an example of an apple ripening anything under experimental conditions. ...

Per Raffaele Porta et al. in 2013, edible coatings was to found be extremely advantageous to preserve the characteristics of fresh-cut fruits and vegetables at their peak. A review of various preservative treatments for color preservation and preventing texture loss in fresh cut fruit and vegetables can be found here.

Update #1:

Dark storage limited the decrease in juice asparagine to some extent. Aromatic lactones, such as gamma-decalactone and gamma-dodecalactone, both in skin and in flesh tissues increased more rapidly when the fruits were stored under a light condition, irrespective of fruit harvest stage. From these ...

This has been pretty well debunked by Snopes.
If such a flower or fruit actually exists outside of folklore, it's unknown to botanists. We haven't found reference to such a plant in any handbooks or textbooks of botany. That having been said, neither are there obvious signs that the images and video have been tampered with, which leaves only one logical ...

Emblica officinalis (of the family Euphorbiaceae) also known as Indian gooseberry in the form of fruits contain mostly carbohydrate with moderate fiber content and are rich in vitamin C, with some other unique bioactives. Emblica officinalis extract is Generally Recognized As Safe as a food additive by FDA.
The effects listed below were noted in ...

Lemons are a fruit and contain a variety of compounds both in the pulp and the skin. Some of these organic molecules can have effects in human physiology, but the scientific information available indicates that eating lemons or drinking lemon juice will have no direct substantial effect on curing cancer.
If scientists are studying specific compounds also ...
