Names, Surnames & Titles

Keeping the names of angels

Q: Are we allowed to name our children after angels (e.g. Jibraeel, Mikaaeel, etc.)? If we are allowed, then should we name them just Mikaeel or does the name have to be accompanied by a forename such as Muhammad, i.e. Muhammad Mikaeel, Muhammad Jibraeel?

The name "Thurayyah"

Q: My brother and his wife will be having a baby girl soon and he wants to name his daughter Thuriyaah Insha Allah. I am unable to find a meaning for this name. I have found Thurayaah but this is not the same.

The name "Umayr"

Q: I would like to confirm the name "Umair or Umayr". This would be after the first Ambassador of Islam Mus'ab ibn Umair (Radiyallahu Anhu), who was sent to Medina by Nabi Mohammed (Sallallahu Alayhi Wasallam). Can you please confirm if this meaning is correct and what is the correct transliteration spelling, Umair or Umayr?
