* Kamusta? (This is a more informal and friendly way to greet someone.)
* Musta? (This is a very casual and slangy way to greet someone.)
Other options:
* Ano ang lagay mo? (This translates to "How are you?")
* Mabuti ba? (This translates to "Are you well?")
It's important to note that the level of formality you use depends on your relationship with the person you're greeting. For example, you would use Kumusta po? when greeting someone older than you or someone you don't know well. However, you could use Kumusta? or Musta? when greeting a close friend or family member.
