Tempest II is a Cloak & Dagger character, III is a Ghost Rider character.
Angel was depowered on M-Day in Exiles (1st series) #71. She became a tech-based hero with the New Warriors as Tempest in New Warriors (4th series) #1-2. Angel used elemental gauntlets allowing her to produce flame, ice, or winds.
Angel regained her mutant abilities at some point prior to New Mutants (4th series) #3. Her husband Beak was repowered by the Mothervine effect in X-Men: Blue #26. It's likely Angel was repowered behind-the-scenes by the same effect.
