Start with your five daily prayers. They are Fardh (obligatory) upon us to pray them everyday at the specified times.
There is Fajr (Dawn prayer) - 2 Rakat
Dhuhr (Noon) - 4 Rakat
Asr (Afternoon) - 4 Rakat
Maghrib (Sunset) - 3 Rakat
Isha (Night) - 4 Rakat
You need to look up the timings for these based on your specific location. You can find them easily, in shaa Allah (if Allah wills).
Learn these firstly, they are very important. After you have learned them, you can find out about the other voluntary prayers, in shaa Allah. Don't confuse yourself with an overload of information. Start with the basics and what is Fardh upon us to do, and then move on.
