Can this Koji be used to make Miso?

Yes you can, the Koji-Kin(fungus) you can grow it on the the grains after steaming them in a tub. I use a tub with waterbottles filled with hot tap waters. the temp needs to be around 80-86 degrees to grow for 30 hrs. make sure to gently move the rice around every 10 hrs to get it to grow evenly across the rice. I used plain medium white grains. before you steam the rice be sure to wash the rice in a plastic tub until the water is clear.Miso (みそ or 味噌 ?) is a traditional Japanese seasoning produced by fermenting soybeans with salt and koji (the fungus Aspergillus oryzae) and sometimes rice, barley, or other ingredients.

Can the Koji sit at room temperature for a few days without spoiling?

If you mean after the Koji mold has been incubated on the rice, then I would suggest refrigerating it once it's reached the desired maturity. At room temperature, it will likely continue into full maturation (turning green) and begin sporing. Many people will spore a small portion of their koji'd rice in order to have their own spores for future batches.

Can this be used to make barley koji? I want to make my own koji to then make miso. Thanks!

Yes. These are Aspergillus oryzae spores. You can grow them on whatever grain, legume, or other appropriate substrate that you choose.
