The three players had been granted a few extra days to recover before linking up with the national team following Saturday's Champions League final in Lisbon where Real defeated city rivals Atletico 4-1.
Ronaldo, who was still feeling the effects of a thigh injury sustained late in the season, was not expected to take part in a late afternoon training session and remains a doubt for Saturday's friendly against Greece in Lisbon.
The Portugal captain instead carried out rehab work at the team's hotel, the Portuguese Football Federation (FPF) said in its daily medical report.
Having played 120 minutes in Saturday's Champions League final, Ronaldo had admitted he "wasn't at 100 percent" having struggled with muscle problems towards the end of the La Liga season.
Portugal have been drawn in Group G at the World Cup and will face Germany on June 15 in Salvador, the United States a week later in Manaus and then Ghana on June 26 in Brasilia.
