In Lightroom, a common workflow is to edit one photo in Develop, then select the others and use Sync to apply the same settings. After that, select the group and use File > Export to create JPEGs.

If you want a consistent starting point, you can set Lightroom defaults or a custom import profile so new RAW files get the same initial treatment automatically.

Lightroom will render the RAW file when exporting to JPEG, so the result won’t be a byte-for-byte match to the camera JPEG. By default, Lightroom does relatively little, though mild sharpening may be applied depending on your settings. If you simply import and export without editing, Lightroom generally won’t make major visual changes, but it still uses Adobe’s RAW rendering rather than Nikon’s in-camera processing.

If your goal is to match the Nikon in-camera JPEG look as closely as possible, the best option is usually Nikon’s own RAW-processing software, since camera makers often use proprietary processing for their JPEG output.
