Naja is from the Kalaallisut (West Greenlandic Inuit) Naja — meaning "little sister" (term of endearment). Naja in Greenlandic tradition — one of the most-popular feminine names in modern Greenland (Kalaallit Nunaat); the name reflects the Greenlandic cultural emphasis on familial connection and feminine kinship; Greenland is the world's largest island and one of the only places in the world where an Indigenous language (Kalaallisut) is the official national language. Naja in Hindi/Sanskrit — also used as a Hindu unisex name from the Sanskrit nāga (serpent, dragon); the iconic genus Naja in zoology refers to true cobras. Princess Naja — modern Greenlandic heritage naming.
Naja does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Naja reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
