Writers, showrunners, and crew, believing until the very last scene of the last episode was being written that the fifth season would be the last, filled the series wall to wall with meta jokes, references and callbacks to past episodes, shoutouts to cast, crew and family, subtle, overt, and openly cheesy and/or deep symbolism and nerdiness, and anything else they could get in from their -and fans' - bucket lists. Including sneaking in references to the season and episode numbers in each relevant episode. The number 5 comes up at least once per episode in 5a. See more
SPOILER: Within the show, one of Lucifer's other names is said to be Samael, which characters translate as "Lightbringer". However, Samael means "Poison of God", and is a different angel. If the intent was to keep to the in-universe naming pattern of using angel names with the '-el' suffix, the closest one associated with Lucifer is Helel - "The Shining One". (But a name with "Hel" in it could be considered way too on the nose under the circumstances).
Also, given that "Lucifer" as a name for the Devil and "Helel" as an alternate name for Lucifer are both the result of misinterpretations of early text, the 'error' could be taken with a grain of salt. See more
