It depends on the context of the sentence.
It's like English. A same word can have two or more meanings, depending on the context, e.g please can mean: 1. ask for help 2. to satisfy someone
It's the same in Swedish. For example, "tack" can mean: 1. thank you 2. please depending on how you use the word. Hope the explanation helps you!
The voice is not quite perfect on this sentence, as of May 10th, 2018, so I've taken the liberty of re-recording it.
This one has a small, simple error - it says ve rather than vi. And while Swedish will quite often use somewhat different vowels in everyday speech than in what a language course is likely to use, that's not the case here. :)

Thanks for listening. Ha en bra dag! :)
Actually, now that I've read through the comments, I'm wondering what exactly is being said here? Are we all, collectively, eating from the same lunch? Like a picnic? Or is this referring to a lunch break, for example, where multiple people are eating 'our lunch' even though 'our lunch' is, in fact, several individuals' lunches?
In the second case, I would think this should read 'vi äter våra luncher,' as seen in Arnauti's comment above...
