In the latest incident, state-owned Al-Ahram newspaper reported on its website that two men were shot dead when assailants attacked a sit-in by the deposed Islamist's loyalists near Cairo University early Tuesday.
A hospital official confirmed that two bodies were received early Tuesday morning.
The morning violence came after Morsi's supporters battled his opponents with stones and birdshot near Cairo's Tahrir Square the previous evening, leaving one person dead.
Another three people died Monday night in violence in Qalyub, north of Cairo, one of them hit by a train as he tried to escape the clashes.
Morsi's Muslim Brotherhood said a loyalist was killed in northern Cairo, when police clashed with pro-Morsi protesters. The death could immediately be verified.
His Islamist supporters have vowed to continue protests until he is reinstated.
Although mostly peaceful, the pro-Morsi protests have resulted in deadly clashes, with the unrest claiming more than 100 lives in all, according to an AFP tally.
In the bloodiest single incident, at least 53 people died, mostly Morsi supporters, during clashes with soldiers outside the elite military barracks where they believed Morsi was being held.
