To add the normal stress in the x-direction, in the solution sub menu go to Stress > Normal. In the details view window ensure that the Orientation is set to X Axis. Let's rename the stress to "Stress_xx" by right clicking the stress, and going to rename.

Now let's add the theta stress. This is too a normal stress, so create a new normal stress as you did for Sigma_xx and Sigma_r. Now, change the coordinate system to Polar Coordinates, as you did for Sigma-r. Next, change the Orientation to the Y axis. The Y axis should be in the theta direction by default. Rename the stress to Sigma_theta.

Tau_r-theta

Finally, let's add the shear stress in the r-theta direction. To do this, we go to Solution > Stress > Shear. You'll notice that now, in the details view window, the stress needs two directions to define it. In order to solve for the r-theta shear, we need to change the Coordinate System parameter from the Global Coordinate System to Polar Coordinates. Also, ensure that the Orientation is in the XY direction (in polar, this will be r_theta by the coordinate system we created). Rename the stress to Tau_r-theta.

This is what your outline tree should look like at this point:
