Eleven of the 16 people injured in Saturday's attack remain in five Kraków hospitals, with their condition steadily improving, regional governor Krzysztof Jan Klęczar said on Thursday.
Two other victims are receiving treatment in Warsaw and Vienna.
Among those still hospitalized is 27-year-old police officer Artur Morański, who was shot twice during the attack.
He underwent surgery on Wednesday at a military hospital in Kraków to repair damage to his elbow.
His condition remains serious but stable, and further operations are planned.
Meanwhile, daily life is returning to Kraków following four days of official mourning.
Buses and trams were crowded with commuters on Thursday morning, while cafés in the city center welcomed their usual breakfast customers, Polish state news agency PAP reported.
"Kraków is gradually returning to its daily rhythm," City Hall spokeswoman Patrycja Piekoszewska said. "The city is functioning normally. Although the attack remains a difficult experience, we are trying to live normally."
Klęczar said regional authorities were preparing assistance for the injured and the families of those killed.
Officials in three provinces were contacting local governments to assess what support may be needed.
Psychological assistance was provided immediately after the shooting, but authorities have yet to receive formal requests for further help.
Funerals for the victims have begun.
A book of condolences remains available at Kraków City Hall on Wszystkich Świętych Square until Friday.
On November 7, a 24-year-old man drove onto the Main Market Square and opened fire on pedestrians.
Six people were killed and 16 injured, including two police officers and the attacker, who died in a hospital on Monday.
Investigators believe the gunman also killed his parents and sister at their family home in Ostrowiec Świętokrzyski, about 170 kilometers northeast of Kraków, before traveling to the city.
The attack also prompted a wave of online disinformation, including false claims that the police were slow to respond, that a second gunman had been spotted on the roof of St. Mary's Basilica, and that the attacker was a Polish soldier.
Digital Affairs Minister Krzysztof Gawkowski said authorities were monitoring the spread of false information and taking steps to counter it.
