Yes.

Yes, and some of us still do. It's called Asatru.
The Aesir were the main Norse gods, consisting of all the well known gods such as Thor and Odin. The Vanir were nature and fertility gods, and they were not as well respected in Norse mythology. In the way of worship, the Norse people believed their gods were more like mighty beings deserving great respect than they were actual gods. In fact, the Norse believed that their gods could actually die! Due to this, neither the Aesir or the Vanir were actually worshiped, at least not they way most other cultures worshiped their gods, they were just respected, asked for guidance, and sometimes prayed to for help. Both of the races in the Norse Pantheon were treated the same way by the Norse people, although, as I said, the Aesir were slightly more respected.
