I hope that Victoria and Daniel surprise us again and give the child a first name we would have never guessed.
I think Albert, Henri, Edmund and Sigvard aren't very likely as first names, because they are the names of the sons of the Magnuson brothers, all younger than Estelle, born in December 2012 - October 2015.
I hope that Olle or Gunnar from Daniel's father will be included in the name.
About the godparents, I predicted before the christening of Nicolas
Princess Madeleine
Queen Mathilde
Hereditary Prince Hubertus of Saxe-Coburg and Gotha
Gustaf Magnuson
Hedvig Blom or Caroline Kreuger Nilsson
But because Gustaf was chosen as a godparent for Nicolas, maybe Victoria and Daniel choose another relative instead of him.
