Pedantic Conchy point of religious order(s)... it's gods and devils... plural.

Robert Johnson's is the Yoruban Vodun Papa Legba, Iwa or Loa to the underworld.

Johnny's is the mainstream Western media Christian Devil (aka: Beelzebub, Lucifer, Mephistopheles, Satan &c &c &c.) The Great Deceiver.

Others mentioned above had their own players going right back to Orpheus and beyond no doubt.

But only if the particular God under discussion wills one to adopt the rules of the particular faith. Otherwise, it's all just fairy tales and anything is possible. Different ships, different long splices and all that.
