Formal:
* Kumusta po? (This is the most common and polite way to ask someone how they are.)
* Mabuti po ba kayo? (This translates to "Are you well?" and is also very formal.)
Informal:
* Kumusta? (This is a shorter and more casual version of "Kumusta po?")
* Kamusta ka? (This is a very informal way to ask someone how they are, used between friends or family.)
* Okay ka ba? (This translates to "Are you okay?" and is a good way to ask someone if they are alright.)
Other options:
* Ano ang lagay mo? (This translates to "How are you doing?" and is a more casual way to ask someone how they are.)
* Kumusta ang araw mo? (This translates to "How is your day?" and is a good way to start a conversation.)
Note:
* The "po" at the end of phrases is a sign of respect and should be used when talking to someone older or in a position of authority.
* The use of "ka" instead of "kayo" is more informal and should be used when talking to someone younger or who you are close to.
No matter which phrase you choose, it's important to be mindful of the context and the person you are speaking to.
