Why does the Navi give their names and characters?
Radak: It foretells about the actions they will do.

What is "Chalbi"?
Rashi, Targum Yonasan: He is from Kalev's house.
Refer to 25:3:5:2.
Kli Yakar: His primary name was Kalbi. (People called him Naval due to his lowliness.)
Why is his name written Kalbo, and we pronounce Chalbi?
Radak #1: It is written like k'Libo - his deeds were bad, just like his heart. Perhaps also the pronunciation hints to k'Libi - one who requested from him would say, he refused, like I thought [in my heart] that he would.
Radak #2: We pronounce it Chalbi - due to the lowliness of his deeds, he is attributed to a dog.
