yes you can. it will help you get into college.
If you're going to a college that wants SAT scores, then yes.
there are colleges that now accept ged's , make some phone calls to colleges in your area to see if they are one that will accept your ged. Some colleges have you take sat exams to enter school but there are smaller ones that don't require sat testing.
you can but not on the real sats
Sure you can take your SAT's. Contact the local high school in which you should have attended and asks them when they offer the exam so that you can take it. It may cost you $25 dollars or so to do. No limitations other than you will miss any review given for free at the high school. A local SAT preperation manual purchased at any book store or Kaplan offers alternate review for about $500.00.

Yes. Your SAT and ACT scores will carry more weight.
Possibly. You'll need to have a good score on your GED but they'll also want you ACT and/or SAT score as well. I just got my GED (I want to apply to PITT) and now I have to find out where you take the SATS so you might want to look into that if you haven't taken those tests already.
You must have a high school diploma or a GED before you can even apply to a college. You will also have to have certain scores on the ACT or SAT tests. Some colleges will allow you to take the COMPASS test if you never took the ACT or SAT.
Many junior colleges have an open admissions policy, meaning that anyone who has a GED or other high school degree will be admitted. Such junior colleges do not require a student to take the SAT or any other standardized test in order to be admitted.
You can still go to college if you get your GED or diploma. At a minimum, most colleges require a GED or diploma to attend. Many require SAT or ACT scores.
You should take it in High School preferably in your late Junior year and early Senior year. That way you can send your SAT/ACT score to colleges and universities to look over.
