Friends often use 吃了吗？or 哈喽

你好, is commonly used in first meeting with new friends or people instead of 你好嗎. Normally when intruced to new people, you may use 幸會（xinghui), or 久仰 （'jiuyang', if the person is well acknowledged in certain community or professional area.)
You may also just say '早上好‘(colleagues)， ’您早啊‘（older aged)， ’早安‘ or '早啊’ （neighbours) '午安‘（noon or early afternoon) ’晚上好‘ (good evening).

rather smth like 吃了没 or smth with eating context

it is very uncommon to greet with 你好吗

add to this 哟 and 嗨

nowadays they also greet 哈喽（ha lou)or 嗨（hai）which sounds same as hello/hi
