Hi Rihab, The word 'lesson' doesn't necessarily mean a group lesson. It can still be a private one to one session. Some teachers do group lessons, and some do one to one. Also with some teachers you can book a package of five or ten lessons OR you can just book one lesson. Some offer 60 minute lessons. Others do longer or shorter lesson times. If you have any doubts the best thing to do is send the teacher a message and they will normally be very happy to answer your questions (you are a potential client!).

You can either buy a package (what I assume you mean by subscription), or you can just book a single lesson at a time. There should be a separate option for the package unless you're only looking at a particular teacher who only offers packages (I've never seen one that does).
