The cases against people relating to the demonstrations in support of Gaza in December 2008 and January 2009 are continuing.
Eighteen defendants appeared in court on Wednesday of last week.
Some have more than one charge brought against them.
All face at least one charge of violent disorder.
There are over 50 cases that have gone to the crown court either for trial or sentencing.
Miriam Hamid, Nizamul Jalal and Sulaph Ridha are all accused of violent disorder relating to an incident in Starbucks cafe on Shaftesbury Avenue on 17 January 2009.
Sulaph was the only one of them to plead not guilty.
The prosecution pointed the judge to the sentencing of Layla Lahouidek, 19, and Bana Hablegiorge, 20, as a guideline.
The two women were sentenced to 15 months in prison after the same incident.
Judge Denniss warned many of the defendants that “it is extremely likely that you will receive a custodial sentence which will deprive you of your liberty.”
The judge recommended that the barrister for Andris Feodorous, pleading guilty to violent disorder, read the judgments of the trials after the Bradford riots in 2002.
Judgements then saw around 50, mostly young Asian men, given heavy prison sentences.
