Also, when you change them next time, change only one string at a time and string it like the rest of the strings which are still on the guitar.

Sorry we can't be more helpful, but this sort of thing is extremely difficult to explain in words. The best idea is probably to do just what you are going to do; that is, get someone to show you.

I have no idea what you are talking about here... "sounded really weird"? "there virbrating"? That's a good thing!!! Unless you mean that they're buzzing, which is bad.

"the bridge those metal holding things are lose now" - (I won't comment on your parsing...) those metal holding things are called "string saddles". You'll want to make sure that the string is sitting in the little groove on the saddle. It'll hold it down and then they won't be loose anymore.

If the electric tuner isn't picking anything up, it isn't because the strings are defective or that you strung it wrong. Is the volume on your guitar all the way up? Is the tuner set to "Auto"?

BTW, how old are you?
