Dear @Gago,
Welcome back to the Wefugees Community and thank you for your questions!
Unfortunately, I have to agree with @Kesskester28 in his point that you need to hold the temporary residence permit for at least 5 years before you have a chance to obtain the permanent residence permit (Niederlassungserlaubnis). Please see the full list of requirements here. As far as I remember, you held a Duldung before you received the residence permit last year, right? Nevertheless, I am very happy to hear that you eventually managed to obtain the residence permit in the first place! This is really a great step forward and I don't have any doubts that you will manage in the future to successfully apply for the permanent one as well!
Regarding your second question: No permanent residence permit is issued automatically. Your wife has to apply for it (children can obtain one from the age of 16 y.) and fulfil the here listed requirements as recognised refugee. Please note that in general "the proofs of income may also be provided by the spouse or same sex partner in the event of marital or civil partnership cohabitation".
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
Meike
