Three passengers boarded with their masks down. I asked them to pull them up. When collecting trash; before door closure; I noticed passenger in XX4 mask down again.  I asked her again to pull up mask and advised of policy; she laughed at me; then mocked what I had said. I asked again if she would pull up mask. Then advised the Captain of the interaction since I had to speak to her twice while on ground. Passenger in YY3 had mask down for second time in cruise when I collected trash after service.  He claimed he was forgetful. XX4 passenger played the peek aboo game where she had mask down but each time I approached; before I reached her; would pulled it up. ZZ4 passenger asked me how many times I was going to ask him to pull up his mask. When deplaning; had mask down.
Flight Attendant reported three passengers would not comply with face mask policy.
