Best not to risk joining them in the drink. Give them encouragement and advice, but dont sacrifice yourself. Often it id the rescuer and not the rescued that suffers death when water is involved.

Once they are clear of the dangerous thin ice, strip them of their wet clothes and place the two that just got out of the icy water into your snow cave next to the fire. Strip down yourself and gather them into a bundle around you.sothatthey can start to get their core temps up to yours.
