Nope they were not MSSJ.
The timeline of movie 8, is mid-rosat training(Goku and Gohan).

"When, exactly, would the characters have been "pulled" from then? Movie 8 was released in March of 1993. Three months before that would be December of 1992. The first episode that aired in that month was Episode 167, in which Cell announces the Cell Game. This is one episode before Goku and Gohan re-emerge from the Room of Spirit and Time. The Movie began production before Gohan and Goku had finished their training, and had certainly not yet shown what kind of power they had in this "full power" state. Would this not mean that the characters are based off of the period of time in which Trunks and Vegeta are fighting Cell? We actually see Goku and Gohan during this fight, training in the Room of Spirit and Time. In the Manga, the last time we see them training, Gohan has just had his hair cut and can turn Super Saiyan. His hair length is suspiciously similar to how it looks in Movie 8. His bangs are shorter than in the Cell Game and the back has little spiking. Without doubt, the length of Gohan's hair in Movie 8 is closer to when we see him in the Room of Spirit and Time then it is in the Cell Game.
"Mid-RoSaT". The characters were extracted from the point in time in which Goku and Gohan were still training in the Room of Spirit and Time. This would be about the point in which Goku shows his ability to tap into the 2nd and 3rd type Super Saiyan transformations. They've been training enough to increase their power hugely, but not yet begun the regimen to relax themselves while transformed and hold the state all the time. The way the battles play out in the movie enforce this, because if the movie was "Post-RoSaT", there would be a huge gap between every protagonist fighter, but they all seem to be on relatively equal footing. Also, if Gohan had completed his training, he would be on the tip of being able to go past the Super Saiyan. However, despite the circumstances and how dire they become, there is no such hint at this. If he was capable, Goku would have been pushing for that instead of the odd way he goes about besting Broli. This means Gohan was not yet ready to fully tap his true Super Saiyan abilities.
Movie 10, as well, enforces this. When Gohan is fighting Broli, he notes to himself that his opponent is every bit as strong as before, and then mentions that he himself has powered up considerably since then. If Gohan had finished his training in the Room of Spirit and Time, there would be something horribly wrong with this statement, because Gohan had lost a large amount of power during the 7 years after the Cell Game. On top of that, when Gohan goes Super Saiyan, he holds out against Broli better than anyone did during Movie 8, proving that he himself had not only become stronger since then, but was greater than where everyone else was at the point of movie 8."
