Rae- adorable, timeless, ages well! Rae is perfect, and even though it is short, it doesn't need a longer name. But it does need a longer middle name, perhaps Rae Vivienne or Rae Julianne
Alice- my all time favorite name. It has everything a name should, and for middle names I like Alice Bernadette or Alice Isabelle.
Nell and Nellie- I don't really like these. Nellie is cute, but is a little too childish.
Ruth- like it. Maybe Ruth victoira or Ruth emmalyne
Marjorie- ew, just use Margaret.
Jane- same thing as Rae, timeless, classic, elegant. Janie could be the nickname for a child. Maybe Jane Eloise or Jane Amanda,
Henrietta- doesn't suit a child well, and a little too out of date.
Sybil and Veda- seem a little too made up scimfi for my taste. But some people really like that, so it is up to you. But Veda is much more feminine than Sybil.
