Without permission, yes.
It may be, depending on the license agreed to.
Copyright infringement is a violation of federal law, and can carry significant fines. Schools often take it upon themselves to identify, punish, and correct infringing actions before they reach that level. Many schools also address copyright infringement and plagiarism in their honor codes.
right now: YES! It'd be copyright infringement.
No it would not be a copyright infringement. Copyright does not protect names, titles, common words/phrases, facts, ideas, systems, or methods of operation. However product names can be, and usually rare, registered as trademarks.
A written policy can be as simple as "faculty, staff, and students of thus-and-such school must obey all federal copyright laws." The larger problem would be in enforcing such a policy--because infringement is so prevalent and simple, preventing it would rely on the honor code of the school.
It depends on the extent of the copying. Bear in mind that using others' content without citation can be plagiarism even if it isn't copyright infringement.
Not likely. Most school logos are protected as trademarks and the original artwork is generally protected by the artists copyright.
You use a search engine to check it out. Type in "book" and list keywords from your book to see what comes up -- if it's too similar, it would be infringement. For example: if you wrote a story about young magicians studying at a special school, that would not necessarily be infringement -- if you wrote about a student with a special mark who was destined for great things and found out he or she was a magician before going to said magical school --- then JK Rowling would have words with you.
Kinder garden school paintings are given to kinder garden children, so you don't need a copyright if you draw inspiration from Disney cartoons, but if you are copying a cartoon print as it is and using it for commercial purpose it will be duly subjected to copyright infringement.
If it's in school, that is considered cheating. In the adult world, it is plagiarism. Normally works of others are normally copyrighted, which could result in you getting sued for copyright infringement.
No ... that is copyright infringement and could be punishable by law. It may be possible, if you state your reasons why you want to use it, like for a school crafts project, they may give you permission. You'll never know unless you write to them.
