Mursi was removed from power by the armed forces in July 2013, following mass protests against his rule.
The defendants are accused of taking part in a protest against the ousted president's rule outside the Qubba presidential palace in February 2013.
Seven juveniles included in the case were also sentenced to five years in prison and five more years under observation.
All defendants were charged with illegal assembly, threatening to use violence, displaying force, protesting without notice, disrupting public peace and vandalising public and private property, Al bawaba reported.
In November 2013, Egypt's then ruling interim president Adli Mansour issued a law to regulate peaceful assembly. The protest law has been widely criticised by domestic and international human rights organisations which say it violates international standards for peaceful protests.
