Meaning of Islamic words

The five pillars of deen and the faraaiz of other Islamic acts

Q: My question is that we believe that there are five Faraaiz in Islam (Kalimah, Namaaz, Roza, Zakaat and Hajj). Then how we categorize that there are different faraaiz in every Islamic aspect like Wudhu Faraaiz, Ghusal Faraaiz, Hajj Faraaiz, Namaaz Faraaiz etc. What is difference in five main faraaiz and then the faraaiz in different Islamic acts. So can we say that there are not total 5 faraaiz but a lot of faraaiz in Islam?
