Yes, we use this character very often in our everyday coloquial Cantonese. Like 佢而家好嬲, 佢仲嬲緊, 你激到佢好嬲 ...It won't sound antiquated, strange or too formal. In written Chinese, we will use 生氣 or 憤怒 instead. So it's a good idea to learn this character to make you sound more like a native Cantonese speaker. The examples you quoted sound like what our parents or grandparents would say.
As a side note, sometimes, we say 嬲嬲豬 to express "angry" in a cute and funny way.
