can i stack a 6 inch riser onto a 12 inch riser to make an 18 inch riser?

Yes you can. They will attach on the side with Stainless Steel screws (not included) just like the tuf-tite lid. You may want to put some 1/16 butyl rope or some other sealing product in between them to ensure a proper water tight seal. This is to prevent rain water from seeping into your tank. Causing more wear and tear over time.

Will this fit on a polylok riser?

NO. Polylok and Tuf-Tite risers are not interchangeable. That also includes the lids. A polylok lid WILL NOT fit on a Tuf-Tite Riser, and vice versa

Is there an adapter to attach this directly to the concrete septic tank? (I currently have no riser)

I don't know, I would check directly with their website. I know you can purchase a flange from a septic supply store that may work. I just used a whole lot of waterproof sealant and made a nice fit against my tank.

What is the outside diameter of this?

The Outside diameter is 25.95" You can view the specs pdf here tgwastewater.com/blog/wp-content/uploads/2014/06/ALL-24-drawings.1.pdf
