Alaikumassalam wa rahmatullah,
Hunaydah (هنيدة) is an Arabic word that means “100 camels”. Since camels were a symbol of wealth, it is like calling the girl “jewel”, suggesting that she is valuable and precious.
As for Huwaydah, it is the feminine of Huwayd, which is an Arabic name taken from the Persian word Huwaydaa, which means “clear”, “manifest”, “apparent”. It is an acceptable name for Muslims since it has a good meaning, but it is not Quranic.
