Yes I haven't had a problem with them.
I believe they are but not together. You have to buy them separately. Maybe because Nintendo wants you to mix and match them?
No, you must buy a Joy-Con Grip separately.
They accept Amiibo scans. You have to enable it in the game and than scan it on the controller stick.
Thats a hard question to answer since the company doesn't let us know when we should get more. We find out when they arrive in store. Same thing with any systems or controllers. It would be nice if they told us that.
You may choose whether it is new or used, but currently, it is only new.
