If you wish to say 'How are you', you could say 'quid agis', which literally means 'what are you', but means 'how are you'. You could also say 'quid agis hodie' which means 'how are you today'. There are a lot of ways you could answer it and I know a few. Optime means "awesome/great", like you just won a million dollars or something. Bene means "well", and bene satis means "okay/so-so". Pessime means you're doing horrible or something, I'm not sure what the exact word is though.
EDIT:
Quid Agis literally means "what are you doing?", and gets used as we use "What's up?". The answers provided above are right. However, the more accurate way of asking "How are you doing?" would be Quo habes? The same answers apply here as well.
Bene satis literally means "well enough/ good enough". (adverb)
Pessime literally means "worst". (adverb)
