Why are the monochrome LRGB images still in their linear state?

The monochrome LRGB images have also been matched in brightness with the Green image as reference using LinearFit​. All this is typical of preparations done to images prior to colour-combination and further post-processing, and is strongly recommended before proceeding. The images are all still in their linear state, shown below.

Can I combine narrowband data with LRGB data?

Narrowband data captured through filters other than Hydrogen-Alpha and Oxygen-III is not generally used to combine with LRGB data. Some also choose to combine regular Luminance with the likes of Hydrogen-Alpha, for example.

What is the RGB_R channel in Photoshop?

Since my colour RGB image was simply named RGB, the new monochrome image that comes up is called RGB_R, which is the colour RGB image’s Red channel. As the images are all in their linear state, by default, the extracted Red channel is also displayed in its linear state.
