1- First Kalima (Tayyab):
لَا إِلٰهَ إِلَّا الله مُحَمَّدٌ رَسُولُ الله
Laaa Ilaaha Illa-llaahu Muhammadur-Rasoolu-llaah
There is none worthy of worship except Allah and Muhammad is the Messenger of Allah
The first kalima tayyab means the word of purity. The second kalima shahadat is declaration of faith (shahada). The other three kalmas are azkar (remembrance of Allah) which teach the importance of worshiping and asking for the forgiveness of Allah subhanahu wa ta'ala.
