Cloud,
Yep.
Might not sound so great when said Cloud is nicknamed (or depending upon location, pronounced) Clod. Or is unspeakably loud.
Kids called things like Princess-Name with two sets of double vowels are invariably spoiled, have an unerring sense of innate superiority and behave accordingly. As do their parents.
Kids who are known by their initials play up to their parents for sympathy when given attention, demand that everything is done for them as they can't possibly be expected to take responsibility for themselves or just have the initials elongated into a name like Teej or Ceej or Midge (the latter being particularly bad when adenoidal peers make it sound like Minge). Particularly when they have the initials because a father parent wanted a mini-me and gave them their name.
Kiki isn't a 'bad' name, but it makes me think of a chattering parrot.
Biblical/Religious names and qualities aren't bad, but I'm yet to meet a child who actually demonstrates any of those qualities (bearing in mind that most Biblical/Religious characters actually suffered horrendously) and, tbh, I think it's pretty unfair to lumber them with it in the first place.
Any more than two middle names seems to be overkill. I can understand it happening when there are two parents who want to pick something they like, if there's a family name or surname that they want to keep or if there's a historical double barrel that got lost somewhere along the line and they want it back.
I do feel sorry for kids whose parents went for a theme and then obviously ran out of ideas for the last one (or Mum must be on a new relationship and Dad put his foot down) - for example, Ptolomy, Nefertiti and - oh - Nigel.
