Below are all of the named persons in Luke-Acts, giving he language used to introduce them when they are first mentioned. I have divided them into three groups.
The first group contains the 38 persons who are introduced with a phrase of the form "a man named". For example, in Acts 5:1 Ananias is introduced with the phrase, "Ἀνὴρ δέ τις Ἁνανίας ὀνόματι" (But a certain man named Ananias). Acts 18:7 introduces Titius Justus in a similar way: "τινὸς ὀνόματι Τιτίου Ἰούστου" (of a certain man named Titius Justus). Strictly speaking the extra words do not give any additional information about Ananias or Titius Justus, but they do serve to indicate to the reader that the person is being introduced for the first time. Theophilus (or any other reader) then knows not to ask himself questions like, "has this Ananias been mentioned before?", "is this Ananias a famous person whom I am expected to know?", or "Have I met this Titius Justus?". By using a phrase like, "a certain man named", Luke indicates that he is not taking for granted that his audience has background knowledge of the person.

Finally, listed in Group 3 below, are the 25 individuals who are mentioned with no introduction at all. In most cases the person was an Old Testament character or public figure who was famous to the original audience. Patriarchs and emperors, for example, required no introduction because everyone knew who they were.
Group 3: Those who are given no introduction

Luke 5:8 but when Simon Peter saw it
Acts 12:17 "Tell this to James"
Acts 19:9 the lecture hall of Tyrannus
Acts 19:33 Some of the crowd gave instructions to Alexander, whom the Jews had pushed forward.
Acts 17:5 they attacked Jason's house
The mentions of Simon-Peter and James, shown in brown above fit the same pattern. These were two of the most famous members of the early church. Paul took it for granted that the Galatians and the Corinthians knew of them, so it is not unlikely that Luke too expected his audience to know of them.
The implication of all this, Aletheia argues, is that the hall of Tyrannus, Alexander, and Jason (shown in blue above) were also known to the original audience of Acts. Let us look at each of these three cases in turn.
The hall of Tyrannus
Acts 19:9 reads:
When some stubbornly refused to believe and spoke evil of the way before the congregation, he left them, taking the disciples with him, and argued daily in the lecture hall of Tyrannus (ἐν τῇ σχολῇ Τυράννου). This continued for two years....The hall of Tyrannus is mentioned abruptly without introduction. This would make sense if the hall of Tyrannus was a famous venue. We might similarly say, "he sang at the Royal Albert Hall" or "she conducted at the Sydney Opera House". The problem is that Paul would not have been able to afford to rent a venue that was famous across the mediterranean. Some later manuscripts add the word τινός after Τυράννου, so that we get "in the lecture hall of a certain Tyrannus. The western text goes further by specifying that Paul used the hall during the hottest hours when the rent for the hall will have been lowest: "in the lecture hall of a certain Tyrannus, from eleven o'clock in the morning to four in the afternoon". All these textual variants seem designed to overcome the problem that Paul would not have been able to afford to rent a venue that was so famous that it required no introduction.
The problem, of course, disappears if Luke's audience was in Ephesus, where the hall of Tyrannus stood. They would have known the place where the faith was introduced to their city, even if it was a modest venue.
Luke followed the same rules when mentioning places and people. Named places that were well known required no introduction are: Luke 2:1; Luke 2:22; Luke 2:27; Luke 3:3: Luke 4:23, 26; Luke 6:17; Luke 10:12, 13, 30; Luke 11:30; Luke 13:4; Luke 17:11; Luke 18:35; Acts 2:9-11; Acts 4:36; Acts 6:9; Acts 7:2, 4, 10, 11, 16, 29, 30, 36; Acts 8:27; Acts 8:40; Acts 9:2; Acts 9:30; Acts 9:32; Acts 9:36; Acts 11:19-20; Acts 13:4, 6, 13,14; Acts 13:51; Acts 14:25; Acts 16:6-9, 11; Acts 17:1, 10, 15; Acts 18:1, 2, 18, 19, 27; Acts 20:13-15; Acts 21:1, 7; Acts 27:1, 5, 7, 17; Acts 28:12, 13, 15
Lesser-known places are given an introduction:
Luke 1:9 cf Luke 1:21; Luke 1:26; Luke 2:4 cf Luke 2:11, 15; Luke 3:1; Luke 4:31 cf Luke 7:1; Luke 5:1; Luke 7:11; Luke 8:26 cf Luke 8:37; Luke 9:10; Luke 19:29 cf Luke 21:37 & Acts 1:12; Luke 23:33; Luke 23:51; Luke 24:13; Acts 1:19; Acts 3:2 cf Acts 3:10; Acts 3:11 cf Acts 5:12; Acts 8:26; Acts 9:11; Acts 14:6 cf Acts 16:2; Acts 16:12; Acts 27:5, 8, 12, 16, 27; Acts 28:1;
Alexander
The abrupt mention of Alexander in the Theatre of Ephesus at Acts 19:33 has long puzzled commentators. Much is not clear (to us). Was Alexander was a representative of the (non-Christian) Jews. Was he an artisan like Demetrius, as 2 Tim 4:14 might suggest? Was he a Christian, pushed forward to answer the complaints of the crowd? Or was he the town clark (Acts 19:35). The episode is baffling to us, but it need not have been baffling to readers who knew Alexander.
Jason
I argued here that Jason was given the name "Aristarchus", yet Acts, strangely, does not tell us that the two names belonged to the same person. This problem is solved if we suppose that the audience of Acts knew Jason-Aristarchus. The fact that he is mentioned without introduction in Acts 17:5 confirms that he was known to the intended audience of Acts. While Jason was from Thessalonica, there are hints that he did not remain there. He was in Corinth when Rom 16:21 was written, and if he was Aristarchus he was earlier in Ephesus (Acts 19:29) and he later travelled with Paul and Luke (Acts 27:2). We do not know where he settled or in which Christian communities he became well known, so he does not help us to determine the location of the audience of Acts.
Crispus-Sosthenes
It can be shown the Crispus (Acts 18:8) was given the name "Sosthenes"(Acts 18:17). See my article here and further discussion here. Acts 18:17 would have made sense to Luke's audience only if they knew that Sosthenes was Crispus. Since Sosthenes moved to Ephesus (1 Cor 1:1), the Ephesian community of believers would have known him.
Conclusion
Luke expected his audience to already know Alexander, Sosthenes, the hall of Tyrranus, and Jason. Three of these four resided in Ephesus, and the fourth, Jason, may have done. This suggests that Acts was written for the believers in Ephesus.
