"Do you have your lunch?"
Translation:Hast du dein Mittagessen?
I was also having problems, in terms of when should I use "Ihr, euer, or dein" type of "your"?
At some point I stopped and did some research, and I've managed to build this handy table, that really helped me to get things right from there on:
Masc | Fem | Neu | Plu
Ihren | Ihre | Ihr | Ihre | for formal you, when you use Sie
euren | eure | euer | eure | for when you refer to a group of stuff (plural)
deinen | deine | dein | deine | for informal you (du)
This is the table that I organized for the accusative case. Hope it helps.
I'm not a native speaker but I think that if you're using singular it would be just "Hast du dein Mittagessen?", because here "your" translates as "dein" in singular, if you want to ask plural "you", then you would need to say "Habt ihr euer Mittagessen?", and because you're asking a few people "your" needs to be "euer" here. I used this one and it works for me.
Neuter ein-words (ein, dein, kein, etc.) don't take -es endings except in the Genitive case. So it's "dein Mittagessen" instead of "deines."

Thank you very much, that explains a lot.
So the different versions of 'Dein' 'Sie' 'Ihr' relate to the gender of the word preceding and following - as well as plural, Nom, Acc Dative uses? Does anyone have a simple explanation of how that works with particular reference to the word 'Your'? Thanks again!
That has declension tables for all of the possessive pronouns, including the different form of "your."
