Straight factual information may not be protected by copyright at all; the expression is protected. Just as when using research from physical sources like books and magazines, summarizing or rewording the material is not infringing, but direct quotes need to be properly cited. (This is less of a copyright issue and more of a plagiarism issue.)
If what you want to use from the internet is more creative than factual, you just need an exemption in the law or permission from the rightsholder.
Without a license, yes. That is assuming you did not personally compose, perform and record the song yourself, or take a public domain composition and perform and record it yourself, either of which would mean you own the copyright on those recordings and it would not be copyright infringement to use the recording of the song any way you like.
Although putting a notification on it is not required, that can help protect you. Beyond that, the best way to stop people from copying it is to keep it to yourself.
No because characters are not eligible for copyright protection. Only the artistic expression of those characters can be copyrighted.However most characters are registered as trademarks and representing yourself as a trademarked character, without permission, could be considered infringement.
It would be good to source photos that you did not take yourself, although this is not 100% necessary. There might be copyright infringement if you decide to claim it as your own.
No, but you need to say that you do not own Pokemon.
No.
Never give your personal Information on internet..
Nothing. All creative works in the US are automatically copyrighted when first physically made. There are fees to REGISTER a copyright, but registration is needed only if you anticipate a likelihood of commercial use. The "mail it to yourself" idea suggested by a couple of other posters is sometimes called a "poor mans copyright", and has no legal value whatsoever in the US. If a copyright is infringed, and the copyright is not registered, the only legal recourse is to have a court order the infringement stopped - no damages can be sought or awarded. If the copyright IS registered, then there can be damages. There's no 'in-between' area for stuff that's been mailed back to yourself. Copyright law - including 'poor mans copyright' - is addressed by the US copyright office in the link below.
Copyright protection is automatic as soon as the work is fixed in a tangible medium. Mailing it to yourself, the so-called "poor man's copyright," is unnecessary and ineffective.
No, you cannot copyright your voice as it is considered a natural and inherent part of yourself and not a tangible form of expression that can be protected under copyright law.
It depends on your relationship with it. If copyright is the way you make money to feed yourself, it's pretty darn important.
To find out about do it yourself tiling, you can do research on the internet or in books; another good source is to ask a friend that may know how to tile.
