{Sublime Archangel} gives all other creatures exalted. so if I already have another creature with exalted, does it get it twice? for instance, say I have sublime archangel with a knight of glory on the field, then attack with the archangel. would it get +3/+3, or just 2?
Read the reminder text on the Angel ;).
If multiple instances of exalted appear on a card, each triggers separately. When you attack with a creature alone, count up the instances of exalted amongst your permanents, and that's how many +1/+1 bonuses you get for the creature.

oh dang, I see that now. I don't actually have that card, I had just heard of it, which is why I was wondering. thanks a bunch!
If you wish to know what abilities includig Exalted, there is a wonderful stickied thread called "Which keyword abilities Stack?" made by BlackJester. Check it, it's very informative.
