Possible matches:

• Jair Gonçalves Prates — Known simply as Jair; born 1945. He was a Brazilian forward who played in the 1960s–1970s. Records show several domestic clubs over his career; however, prominent historical sources do not consistently list a long spell at Atlético Mineiro for him.
• Jair Ventura Filho / Jairzinho (Jair Ventura is less common; Jairzinho, Jair da Silva de Oliveira) — “Jairzinho” (born 1944) is a famous Brazilian forward who starred for Botafogo and the Brazil national team (World Cup 1970). He did not have a notable spell at Atlético Mineiro.
• Jair Cândido da Silva or other more recent/lesser-known players named Jair — Several contemporary Brazilian players carry the name Jair and have played across Brazilian clubs including Atlético Mineiro at youth or short-term levels. Without a surname or date, it's difficult to identify the exact individual.
