There are six
The Mind Stone
One of two Infinity Stones on Earth, this yellow gem is responsible for bringing the android Vision to life and giving Scarlet Witch and Quicksilver their powers. Before helping create Vision, it was encased in a scepter that Loki used to control minds in The Avengers.
The Mind Stone - Yellow
The yellow Mind Stone is all about mind control. It is seen when Loki uses his sceptre in The Avengers. He can control the mind of whoever the sceptre touches.
The Infinity Gems (previously known as "Soul Gems") are some of the most powerful artifacts in the Universe. Each one allows its owner extreme control over one aspect of the universe: time, space, reality, mind, power, and soul. When all six are directly wielded together, nothing is impossible for their bearer.
As Benicio Del Toro's The Collector explains in Guardians of the Galaxy, six singularities existed before the creation of the Universe. The Big Bang transformed those entities into six separate Infinity Stones.
Thor, the god of Thunder, was undoubtedly the most powerful member of the original Avengers. His power continues to grow in the Marvel Cinematic Universe.
Orb (Power Stone)
This is the stone that actually wrecked The Collector's home in Guardians of the Galaxy. The purple stone gives the wielder incredible power — superhuman strength shooting beams of purple destruction, and possibly wiping out all organic life from a planet just by touching the surface.
Acquired by Thanos
In 2018, Thanos in his quest for the Infinity Stones, went to Xandar to retrieve the Power Stone. After decimating Xandar and the Nova Corps, he acquired the Power Stone and inserted it in the Infinity Gauntlet. He then used the Stone to torture Thor and to obliterate the Statesman.
Other Infinity Stones
Ego Stone (White): The Ego Gem contains the consciousness of the cosmic entity Nemesis and recreates her when united with the other six Gems. The Ego Gem is found in the Ultraverse when the Asgardian god Loki attempts to steal the other six Gems.
However, while each Infinity Stone can accomplish amazing feats and displays of power, the Soul Stone has a strong case for being the most powerful of the six.
This Is Why Marvel Chose Red Skull to Be Tied to the Soul Stone in 'Avengers: Infinity War' "We knew that we needed to do something special with that stone, but we knew that we also needed it to have an emotional connection to the plot."
Thanks to his artificial intelligence, Vibranium-infused synthetic body and the Mind Stone implanted in his forehead, Vision boasts an incredible number of unique powers. He can access and process huge amounts of data in very short periods of time, making him supremely intelligent.
The Scepter, occasionally referred to as Loki's Scepter, was a staff weapon that served as the original containment vessel for the Mind Stone, one of the six Infinity Stones. Gifted by Thanos, the staff was wielded by Loki to lead and command the invasion to Earth.

Thor loses his eye during the earlier parts of the final battle sequence with this goddess. She casually and effortless beats him around the throne room, and then the moment happens. Hela strikes Thor across the face with her sword, literally slicing the eye from out his head right then and there. Brutal.

The Death Stone was a black-colored Infinity Stone native to Battlerealm.
Avengers: Infinity War cut a 45-minute sequence of Thanos destroying Xandar and stealing the first Infinity Stone, the Power Stone.
In Avengers: Age of Ultron, after being partially destroyed by Ultron, J.A.R.V.I.S. is given physical form as Vision, physically portrayed by Bettany. Different versions of the character also appear in comics published by Marvel Comics, depicted as AI designed by Iron Man and Nadia van Dyne.
The Soul Stone was one of the six Infinity Stones, the remnant of a singularity that predated the universe, representing the element of soul. Kept on Vormir and under the protection of Red Skull since 1945, the Soul Stone was acquired by Thanos in 2018 after he sacrificed Gamora.
DC & Marvel's Crossover Universe Made Hulk the Weakest Avenger - IMDb. The Hulk has been called the strongest Avenger given his unparalleled, planet-shattering strength, but within the 2099 future of Marvel and DC's crossover universe, the Hulk would be considered the weakest Avenger (for one specific reason).
Hawkeye isn't the strongest Avenger. In fact, he's probably the weakest member of the team. He's a guy who is good with a bow and arrow, as he admits in Avengers: Age of Ultron. Even among the members of the team who don't have superpowers, Hawkeye doesn't stack up.
2) Captain Marvel
She holds her own with Thanos in hand-to-hand combat for longer than Thor, Iron Man, or Steve Rogers, and takes down his enormous warship single-handedly.
