All three players were part of the Blues' convincing 3-0 friendly win over Austrian club RZ Pellets WAC on Wednesday.
Loftus-Cheek and Chalobah even managed to get their names on the scoresheet along with Bertrand Traore, who netted the opening goal in the friendly.
After the game, Conte said: "We have many young players and all are working very hard. I'm happy about that.
"Ruben is young with great potential. I like him a lot in the position of striker. He can improve a lot because he has great potential, good technique, good personality and he is good one v one.
"It's normal he can improve and normal too that Chalobah and Aina can improve. Aina is showing the Academy is a good school and it is very important for the club. If I can count on these players it's a new source for me."
