Finally to get to your last question about if there will be another temple on earth. What was the purpose of the temple? Was it not the arrangement for pure worship? Showing God's high and elevated moral standards for the people? It was also where sacrifices were offered and accepted to atone for sin. None of this is required today.
The temple was also just an anti-type of the real spiritual temple which is in heaven. That spiritual temple in heaven came into existence in 29 C. E. when Jesus was baptized in water and with holy spirit. Upon Jesus' death the curtain that separated the Holy from the Most Holy was rent in two. That is because God no longer needed the temple arrangement on earth. The Most Holy which represents God's very presence was transferred to heaven, God himself. And 50 days later on Pentecost of 33 C. E. the resurrected spirit son of God, Jesus Christ entered into the spiritual sanctuary in heaven before the very presence of Jehovah God and offered up his blood offering of his perfect human life as a proprietary (or covering) sacrifice for all of humankind's sins, once and for all times. And he now serves as king and high priest in heaven in the real temple sanctuary.
Please read the entire chapter of Hebrews 9 to get an understanding of these things:

In part there it says:
11"However, when Christ came as a high priest of the good things that have already taken place, he passed through the greater and more perfect tent not made with hands, that is, not of this creation. 12 He entered into the holy place, not with the blood of goats and of young bulls, but with his own blood, once for all time, and obtained an everlasting deliverance for us. 13 For if the blood of goats and of bulls and the ashes of a heifer sprinkled on those who have been defiled sanctifies for the cleansing of the flesh, 14 how much more will the blood of the Christ, who through an everlasting spirit offered himself without blemish to God, cleanse our consciences from dead works so that we may render sacred service to the living God?
15 That is why he is a mediator of a new covenant, in order that because a death has occurred for their release by ransom from the transgressions under the former covenant, those who have been called may receive the promise of the everlasting inheritance. 16 For where there is a covenant, the death of the human covenanter needs to be established, 17 because a covenant is valid at death, since it is not in force as long as the human covenanter is living. 18 Consequently, neither was the former covenant put into effect without blood. 19 For when Moses had spoken every commandment of the Law to all the people, he took the blood of the young bulls and of the goats, with water, scarlet wool, and hyssop, and sprinkled the book and all the people, 20 saying: “This is the blood of the covenant that God has commanded you to keep.” 21 He likewise sprinkled the tent and all the vessels of the holy service with the blood. 22 Yes, according to the Law nearly all things are cleansed with blood, and unless blood is poured out no forgiveness takes place.
23 Therefore, it was necessary for the typical representations of the things in the heavens to be cleansed by these means, but the heavenly things require far better sacrifices. 24 For Christ did not enter into a holy place made with hands, which is a copy of the reality, but into heaven itself, so that he now appears before God on our behalf. 25 This was not done to offer himself often, as when the high priest enters into the holy place from year to year with blood that is not his own. 26 Otherwise, he would have to suffer often from the founding of the world. But now he has manifested himself once for all time at the conclusion of the systems of things to do away with sin through the sacrifice of himself. 27 And just as it is reserved for men to die once for all time, but after this to receive a judgment, 28 so also the Christ was offered once for all time to bear the sins of many; and the second time that he appears it will be apart from sin, and he will be seen by those earnestly looking for him for their salvation."
Reading verses 23-27 we are shown that Christ did not enter into a holy place made with human hands, but when he returned to heaven in his resurrected spirit body he entered into heaven itself, and appears directly before God on our behalf. The temple arragement was only a copy of the reality in heaven. And now that the heavenly arrangement is in place, with Jesus Christ already offering his perfect life blood once and for all time for all people, and serving as high priest and mediator between humankind and Jehovah God there is no longer a need for the representation, or the type, on earth the physical temple, that only was a shadow and a representation of the far more lofty and grand spiritual temple that now exists as a reality in heaven:
Hebrews 7:26-28 says of Jesus' human sacrifice which was offered up before Jehovah God in the great spiritual temple in heaven:
"
For it is fitting for us to have such a high priest who is loyal, innocent, undefiled, separated from the sinners, and exalted above the heavens. 27 Unlike those high priests, he does not need to offer up sacrifices daily, first for his own sins and then for those of the people, because he did this once for all time when he offered himself up. 28 For the Law appoints as high priests men who have weaknesses, but the word of the oath sworn after the Law appoints a Son, who has been made perfect forever."
So we see there is no more need for an earthly man-made temple, and there is no more need for a human high priest, of which all were sinners, and they had to firstly offer up sacrifices for their own sins, and then that of the people, and they all grew old and died. The reality of the temple is in heaven where Jehovah God's person resides, and where Jesus Christ, the high priest, who lives forever supplicates for humankind as our high priest before his Father Jehovah God.
