Two of those banned by the club will not be allowed back for five years. A man previously subjected to a Football Banning Order still threatened a steward as part of a tirade of foul and abusive language.
That was a result of the steward requesting they did not drink alcohol within sight of the pitch.
A person who ran onto the pitch during the home FA Cup ties against Reading was arrested at the time and has also been banned for five years.
A further fan who sprayed a steward with tomato ketchup at the same match has been banned until the end of June.
However, a person arrested and charged by Thames Valley Police for allegedly racially abusing a Reading player will be banned for life if found guilty.
The club said: "This type of behaviour is totally unacceptable to everyone within the Club and the vast majority of its supporters."
A person who used social media to say he planned to take pyrotechnics into the Madejski Stadium was searched and found to have a pyrotechnic will be banned for five years.
In a statement the club said ' It hopes that by issuing these Club bans, it will remove a small number of fans who are not wanted.'
