Homogenize similar shots

There’s more than one way to do this. When you select multiple images, you can click the Sync Settings button in the Library module, or the Sync button in the Develop module. Those buttons let you choose which settings to copy from the “most selected” image (the one with the lightest highlight). When you click Synchronize, the settings you selected are applied to all selected images.

Another method is that instead of syncing, you can copy settings from one image and paste to any number of other images. In Develop, you can select one image and choose Settings > Copy Settings, select the settings to copy and click Copy, select one or more other images, and choose Settings > Paste Settings. In Library, the same commands are on the Photo > Develop Settings submenu.

If the goal is to make inconsistently exposed images look like they have the same exposure, in the Develop module you can try Settings > Match Total Exposures. This typically does not apply the same settings to all selected images, because the goal is to give them whatever different adjustments they need to try and make all their exposures appear uniform.

Are you using auto white balance in the camera? If so, go to a fixed or custom value.

Studio strobe lighting or something else?
