Galimov suffered severe burns and died of his injuries Monday at the Vishnevsky Institute of Surgery, hospital officials said.
The Yak-42 aircraft, carrying the Lokomotiv Yaroslavl hockey team, crashed just after takeoff Wednesday near the city of Yaroslavl with 45 people on board.
Many of those on the team's roster had ties to the National Hockey League, including Josef Vasicek, Jan Marek and Karel Rachunek as well as former NHL defenseman Karlis Skrastins and Swedish goalkeeper Liv Stefan.
Demitra, 36, played with the Kings during the 2005-06 season, finishing third in team scoring with 62 points.
The 3-time All Star last played in the NHL with the Vancouver Canucks during the 2009-10 season.
The Kings issued this statement Wednesday: "The Los Angeles Kings organization is deeply saddened with the tragic news of this morning’s plane crash in Russia that was carrying the members of the KHL’s Lokomotiv organization, including former Kings forward Pavol Demitra, former Kings prospect Jan Marek and many other members of the NHL Family. Our thoughts and prayers go out to all the family and friends of those affected by this terrible occurrence."
Salei, 36, has a home in Orange County, where his wife, Bethann, and daughters Alexis, Aleksandra and Ava, reside.
"The Anaheim Ducks organization is shocked and saddened to learn of the passing of Ruslan Salei. 'Rusty' was a fan favorite and dedicated member of the Orange County community since being drafted by Anaheim in 1996," the Ducks' statement said.
"Our thoughts and prayers go to his wife and three children, along with all of the other members of the hockey community affected by this horrible tragedy."
Salei was the club's all-time leader in games played among defensemen (594).
He scored one of the most memorable goals in team history, scoring in overtime to give the club its first win in a Stanley Cup Finals game (a 3-2 victory over New Jersey on May 31, 2003).
The aircraft was headed from the city north of Moscow to Minsk in Belarus when it crashed, an official at state aviation agency Rosaviatsia said.
The plane was carrying members of a Continental Hockey League (KHL) hockey team based in Yaroslavl, Lokomotiv, to a match in Minsk, Belarus, KHL president Alexander Medvedev said in televised comments.
"There has been a terrible tragedy," Medvedev said after the opening match of the league's season in the city of Ufa was interrupted when news of the crash came. He announced a minute of silence and postponed the match.
Locomotiv Coach Brad McCrimmon, a former NHL defenseman who worked as assistant coach with the Detroit Red Wings, also died in the crash.
The crash was the deadliest in Russia since a Tupolev Tu-134 jet crashed while trying to land in fog in the northern city of Petrozavodsk, killing 45.
