New Android user questions

http://www.mobileread.com – I do have a Kindle Fire HD, but that is not a full android unit, so I have some questions. Can I take an App I bought from Amazon and load on my Samsung Galaxy Player 5? How do you do that? I need to use a stylus that works on a Paperwhite, KFHD, and SGP5. Is that possible? So many questions.;) (HowTos)
