Aiman is from the Arabic aymān (أيمن — fortunate, blessed, on the right hand — auspicious side). Aiman Khan (born 1998) is a Pakistani actress and model — widely considered one of the most-celebrated young Pakistani actresses of the 2010s. Identical twin sister of Minal Khan — the Khan Twins are one of the sister-celebrity pairs in modern Pakistani entertainment. Debuted at age 11 in Meri Beti (2009).
Aiman 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 Aiman reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
