Here are a few useful resources for students of the sacred sciences who want to understand the use of punctuation marks (ʿalāmāt al-tarqīm) in the Arabic language. Students will notice, for the most part, that the rules are similar to European languages.
The following work, authored by Aḥmad Zakī Pāshā (Bāshā), is the earliest work on the subject that I have come across. This edition was published by Shaykh ʿAbd al-Fattāḥ Abū Ghuddah’s publishing house and with his preface. It should suffice most students as a reference.
al-Tarqīm wa ʿAlāmatuhu fī al-Lughah al-ʿArabiyyah li Aḥmad Zakī Bāshā
A colleague at Darul Qasim suggested the following work by his teacher Shaykh ʿAbd al-Muʿizz al-Tūnisī, and friend of my own teacher Shaykh Ramzī al-Ḥabīb al-Tūnisī. The work is not available in pdf format but can be purchased here: “al-Inshāʾ wa ʿAlāmāt al-Tarqīm wa-l-Imlāʾ”
The following web page contains a brief overview of the punctuation marks and how they are used. It can be useful for a quick review:

Do you know of any good places to learn Arabic in Lahore?
Unfortunately, I do not. Perhaps some other readers of the site will know. If you are interested in full-time studies, you may want to consider studying Arabic at one of the branches of Jāmiʿat al-Ḥasanayn. I believe there may be one in Lahore.
