Some things I've learned about Aether since we're doing a very Aether heavy storyline right now and I had to dig into all the research.
~ People can have different levels of Aether, some have a lot - making it easier for them to use magic - and some have very little or none (From the THM storyline). This being said it seems that all magic is Aether and one has to have some in their system in order to use magic at all. I believe it is stated that Garleans can't use magic because of this.
~ Aether is used in the making of weapons, the more used the more powerful the object (Some crafting quests). Aether can be used for pretty much anything if something needs to be magically imbued.
~ Aether sickness is a decease that happens when there is too much Aether around, some being more sensitive to it than others, it can cause a person to go completely insane if not careful (I still don't know how we all hang out in Mor Dhona, anyone know?)
As for being able to sense Aether, I'm not sure thats like a Six Sense or if that something people even have. I got no lore help there one way or another, but hopefully I helped with your other questions XD
