• In the File Browser thumbnail window select all of the images that should have a white balance similar to that of the already corrected image
• From the File Browser Automate menu choose Apply Camera Raw Settings
• From the Settings popup choose Previous Conversion
• Press the Update button

Depending upon the number of images making up your selection File Browser can take from a few seconds to many minutes to update all of the thumbnails and preview images.

Many Photoshop power users build up a series of  White Balance adjustments for various types lighting and then save them as settings within Camera Raw. These saved settings can then be applied directly to a series of images using the Automate: Apply Camera Settings command. As similar exercise can be undertaken for the other features (e.g. calibration settings, lens adjustment, luminance smoothing, etc). In fact any standard adjustment that you think would apply to a selection of images is probably best applied using the Apply Camera Raw Settings command, especially if it doesn't require that you preview it before hand.
