2. Where does it say stars are the nearest?
3. It does not say the sun sinks in water.
The picture that you posted is the reason why Muhammad thought that salty water and sweet water don't mix. However, he was wrong. The two streams actually mix, although the mixing is a slow process and because of that the waters seem to be separated as you showed in your picture. You can make an experiment in your kitchen using salt and water. You'll prove Allah wrong in no time.
Regarding the moon and the stars:
"He Who created the
seven heavens, one above the other ...And We have adorned
the lowest heaven with lamps ... " (67:3,5)
"And He completed them seven heavens in two days and inspired in each heaven its command; and We adorned
the lower heaven with lamps, and rendered it guarded..." (41:12)
"We have indeed adorned the
lower heaven with the beauty of the stars." (37:6)
Do you not see how God has created the
seven heavens one above the other, and made
the moon a light in their midst, and made the sun as a lamp? (71:15-16)
So, the stars are in the lowest heaven, whereas the moon is in the middle of the heavens, between the third and the fourth heaven, apparently. It is also noteworthy that there is no such a thing as a heaven divided into seven layers.
Regarding the sun sinking in murky water:
Qur’an 18:83-86—And they ask you about Dhul-Qarnain. Say: “I shall recite to you something of his story.” Verily, We established him in the earth, and We gave him the means of everything. So he followed a way. Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people.
Sunan Abu Dawud 3991—Abu Dharr said: I was sitting behind the Apostle of Allah who was riding a donkey while the sun was setting. He asked: Do you know where this sets? I replied: Allah and his Apostle know best. He said: It sets in a spring of warm water.
