Absolutely, just download the two you want to install. I'd actually recommend doing that because certain antivirus programs have certain weaknesses which you could cover up if you find the other right virus protection.
Right now I have Avast! Free Antivirus and Ad-Aware Free currently installed on my computer. The later I would recommend the most. Not sure how Avast! would work on XP but do some research to find another good virus protection for your operating system (Windows XP that is), but be careful!
Each antivirus uses up about 5% of your ram when it is not running. if you install more than one anti virus your computer will become extremely slow
You can install anything on a computer. However if you want your antivirus system to work you need to have one working or none will.

Of course. When you download an antivirus software, you really download the installer of that antivirus not the program. When you double-click on it for install, only then the antivirus program will be "personalized" for that computer, and after that it can't be copied to another computer. When a software is installed some files will be copied in system's folder not only in that software folder.

It is advisable for you to only install 1 antivirus software in one PC. If you happen to install 2 antivirus software in 1 PC and your system hangs, that is because the system is confused and the antivirus software is fighting for dominance. You should remove one of the antivirus and if you want to change to a different antivirus, you must un-install the previous one.

Some viruses are able to turn protection off. Use another antivirus program to check your computer. If you are sure that everything ok try to uninstall the antivirus and install again. If it didn't help call support if you paid for antivirus. Or it the antivirus is free pick another one.
