Police have not yet confirmed the identity of the victims, but said they were men aged between 17, 18, 20, 38 and 53.
Officials are not looking for anyone else in relation to the incident, police have said.
Housing charity Positive Action in Housing said the hotel was used to house asylum seekers and that there were between 80-100 people living there, from countries including Iran, Somalia and Afghanistan.
One resident who asked not to be named, told ITV News he was one of the first on the scene and helped those who were wounded.
"The lift was covered with blood on the floor," he said.
"So I did not take the lift, I went down the stairs. When I reached down to reception there was blood everywhere on the reception floor and the whole area, covered with blood. So then I've seen one of the receptionist, fighting for his life behind the receptionist desk. So I shouted at him and told him to stay calm as possible.
"And I called for help. I ran outside the hotel and that's when I saw another receptionist who was lying down on the stairs, always has been stabbed and gasping for air."
"We heard the screaming and the commotion of everything," eyewitness Matthew Nesbitt told ITV News.
"I saw one gentleman lying on the steps outside the hotel. And he had a stab wound to the torso and it was a lot of blood on the steps."

Another witness, who gave his name as Craig, said he saw a man lying on the ground who looked as if he had been stabbed.
"Following that I saw the armed response moving into the building. I then saw many victims being ushered out and being taken away," he said.
"The first few moments there wasn't a level of fear from anyone around us. I think it's one the things about Glasgow people move towards commotion rather than move away from it. But when we saw the armed police on the scene and we got shouted at to move back, it all got a bit more seriously."

Ms Sturgeon said people’s thoughts should be with those injured.
