1) The Quran says we will be resurrected and there is implication that we will have physical bodies because God says that it is not difficult for Him to make a body constituting of blood, bones, skins and muscles for the second time, when it was not difficult to make us for the first time. God makes it clear to people in the Quran, who doubt that, how will our bodies be back when they rot and nothing is left after a few years. Not only that, the Quran speaks of our skin regenerating itself in hell, fresh skin is produced each time the old skin is burnt of so that pain can be felt. There are numerous implicatons that we will have a physical body, but we do not know whether that body will be exactly like the one we have on earth or not.How do you know angels do not have physical bodies? The Quran talks about angels having wings. Just because Gabriel, the Spirit, appeared as a human to the prophets and others does not mean angels do not have physical bodies of their own. Anyway there is debate about whether Gabriel was an angel or not. Please read the relevant article on the main website. Some Christians believe Jesus was the son of God, does this mean this is true? Just because Christians believe something doesn't mean that is true.
2) Again the Quran talks about food being available in paradise. What is the point of telling us that, if we won't be allowed to eat? Ofcourse we will be allowed to eat! Where in the Quran does it say, that in paradise we won't be allowed to have fun and it is a place where people will only pray? Are you expected to only pray on earth? God says His purpose behind creating us is praying, yet we are asked to pray at certain times of the day and night, with intervals and not continuously! It is true that people will sing the praises of God in paradise, so do we do now on Earth, but does that mean we will do it continuously without any break in heaven? I doubt that. But how exactly are we going to pray in heaven and how much and at what times, these answers are unknown.
Who said that angels do only spiritual stuff? We only know that they do not disobey God. Angels maintain the weather, rain, harvest, writing our records, they protect children and adults from calamities upon God's orders, they have jobs to do and we are told that they are good at what God asks them to do.
3) Are u asking whether paradise will be a physical place or not? Yes, most likely it will be a physical place because God tells us, there will be streams and gardens and thrones on which believers will recline. But I cannot give you a 100% guarantee, but most likely, some aspects of us and paradise will be physical and some aspects will be spiritual. We ,as a creation, and Earth as a place ( there are dimensions we cannot detect with our senses, so maybe we can call them something else other than spiritual, but I have used the term spiritual to refer to these aspects of the Earth for the lack of a better word on my part) are neither fully physical or spiritual now, why must that mean we will be either fully physical or spiritual in the afterlife, we can be a mixture of both spiritual and physical. But the exact properties/characteristics of us (state of our bodies and souls after resurrection) and paradise and hell as a place, in the afterlife are not provided in details in the Quran.
From some of your questions I get the idea that u never read the complete Quran fully even once. I would advice you to do that in a language you understand well. Somethings are clarified at other places in the Quran, and to form a knowledgeble opinion about a topic, you have to read all the relevant verses together. You keep on making subtle comments about Islam, which you extract from secondary sources or other scriptures. But this forum is strictly about discussing Quran and passing comments about the verses of the Quran that are clear. Most of us do not like commenting about things that are not elaborated in the Quran.
