You can start your conversations with Filipinos by saying "kumusta ka?" which means "how are you?" and most of them will respond by saying "mabuti naman, ikaw?" which means "I am good, how about you?"
Here are some of the common phrases you can use to start your conversation:
kumusta ka? - how are you?
Ano ang pangalan mo? - what is your name?
ilang taon ka na? - How old are you?
Saan ka nakatira? - Where do you live?
