It's easier to use something like a mod installer like MCPatcher and others to install them for you as some major updates from Minecraft change where you put them and some mods need special instructions some times.The mod you downloaded should have instructions on where to put them.Be aware, every time Minecraft updates itself the mod your using will probably not work any more and you can wait from days to weeks for the mod to be updated depending on the complexity's of the mod.
Your brother has downloaded a mod. You will need to visit a website explaining what the mod is and how it works to know the recipes.
Yes, they will. You just have to wait until the official mod creator comes out with an update.
It probably won't work and you'd have to get rid of the mod and try and find a more updated one. It probably will work though.
Most will not work in a newer Minecraft update with out being updated itself. You would have to ask the maker of the mod you have now. Only they will know. Every mod is different. Depending on the mod it could just take a day or so or weeks to update the mod so have patience.

you have to go to start, click run, click your .minecraft folder, take the downloaded mod (it has to be zipped) click open archive, then with the .minecraft folder, you find bin go in, and open minecraft's archive, then you move the files in the mod archive folder to the minecraft archives. (some things might be wrong, but that's because i used pure memory to answer this, and i have a bad memory. )
To INSTALL a mod, you go to run and type &APPDATA% and click .minecraft then bin and open minecraft.jar with winrar or 7zip. Then copy all the files from the unzipped mod folder into the minecraft.jar, and delete META-INF from inside the jar. Do all this with minecraft closed. Then close winrar or 7zip and run minecraft! You need the downloaded version to do this.
