They are shorter on the front side - I believe 6" on the other side - easy to make a circle.

I would htink so. I can't see why not. They are concrete.
No, mine were flat along the edges.
I tried adhering these blocks with both Loctite Landscape Adhesive and mortar. The mortar was much more effective and less expensive, though inversely proportional to complexity and mess.
I see a lot of different, individual block types that specify not building above a certain height, most of them on Home Depot's website being less than 2 feet in total height. I think it's because the weight of additional block height may crush blocks below. Also, and probably more importantly, smaller blocks are not designed to hold back any material, like a retaining wall. Even with glue, all glues have a limit and a lifetime. At the end of the glue's life, your wall could come down. Please consider researching the max height specified for walls built with the blocks you choose.
Yes they should be fine to use for a fire pit.
