I went through the list and everything sourced seems alright. I have read those Ahadith many times and am very familiar with them. But the ones which are not sourced seem suspicious because I have not seen them anywhere before. And I have read many books narrating Ahadith on this subject.
The exception is the one which says that the attempts will be made to turn deserts green and the one about the nations gathering against the Muslims as people gather to eat food at a dinner table.
As for the deserts turning green:
Abu Huraira reported Allah's Messenger (way peace be upon him) as saying: The Last Hour will not come before wealth becomes abundant and overflowing, so much so that a man takes Zakat out of his property and cannot find anyone to accept it from him and till the land of Arabia becomes meadows and rivers. (Book#005, Hadith #2208)
As for the nations gathering against the Muslims like at a dinner table:
Narrated Thauban: "The Prophet peace be upon him said: 'The nations shall gather and team up against you (i.e., Muslims) as the predators gather and team up against their preys. A questioner asked: 'Is it because of us being low in numbers at that day?' The Prophet replied: 'No, you that day shall be in great numbers, but you will be as powerless as the foam of the water on the surface of the river, and Allah shall remove any fear from your enemies toward you, and He shall put in your hearts a corruption.'
A questioner asked: 'O Apostle of Allah, what is the corruption?' The Prophet replied: 'The love of life's amusements and the fear of death.'
(Translation of Sunan Abu Dawud, The Book of Fierce Battles - The Gathering of all Nations against Islam, Book 37, Number 4297)"
But for the people leaping between the earth and the sky, there is a Sahih Muslim hadith mentioning Dajjal hopping between the earth and the sky. Just a though, but they might be referring to the same thing. They all refer to a time period close to the last Hour.
It is true that men will begin to look like women and women will begin to look like men. i have seen this as well but I do not know where the reference for it is. I have seen it quoted in some books on signs of the Last Hour many times before. So it is most likely authentic.
