Tapani Espera-noites - Marco Tapani Hietala from Nightwish
Osbórnio Sabá - Ozzy Osbourne from Black Sabbath
Gwor Detestável - Oderus Urungus from GWAR
Matadora Araya - Tom Araya from Slayer
Taiya Tacere - Taija Riihimäki from Tacere
Mórtis Elfsen - Håvard Ellefsen from Mortiis (Tbh I overthinked this one big time: I was first thinking David Ellefson from Megadeth)
Avaliador Simão,
Fido Vistaboa,
Eraque Cantaferro and
Aprendiz Thayer - Paul Stanley, Gene Simmons, Eric Singer and Tommy Thayer from KISS (these guys are standing together near training dummies)
Mellisa Sina - Melissa, an album by Mercyful Fate
Arkadia Moa &
Su Zettai - Moametal & Sumetal from Babymetal, credits to /u/Dropolis for this one!
These were pretty clear, I'm moving on to more speculative ones:
Lira Saraivada - A bit so so, but Lzzy Hale from Halestorm
Edrich Adebo - Eric Adams from Manowar, maybe?
Espalda Espíria - Cristina Scabbia from Lacuna Coil (Bear in mind Chiara is a real-life italian name, and Lacuna Coil was an italian band)
Bonus:
Madeleine Roux... well, Madeleine Roux? (The author or Warcraft novel Shadows Rising)
