Tom Riddle might be very suspicious at first. He is a very intelligent and cautious person. He would likely view time travelers as a threat to his plans or as a strange new phenomenon that he wants to control. So, he could start by trying to figure out their motives and how they managed to travel through time.
Hermione Granger is often a popular character. She can use her intelligence to figure out the implications of time travel and help Harry or deal with Tom Riddle in some way. For instance, she might research spells to counteract any dark magic that Riddle tries to use during their time - traveling encounters.
They can interact as students. For example, if they time - travel to when Tom Riddle was at Hogwarts, they could be in the same classes or clubs. Maybe they join the Duelling Club where Tom Riddle was known to participate. Another way is through chance encounters in the hallways or the library. They could strike up conversations about magic or Hogwarts history.
At first, it would probably be full of suspicion. Tom would be curious about this strange new boy at Hogwarts. As Harry tries to change Tom's path, they might develop a sort of mentorship, with Harry being the wiser one guiding Tom. But Tom could also be jealous of Harry's natural popularity and goodness. Eventually, they could become friends if Harry is successful in showing Tom a different way of life, or they could become bitter enemies if Tom feels Harry is trying to control him.
