Okay, the KV sound is difficult for most English speakers because we keep trying to tuck a vowel between the letters. There is no vowel. You go straight from the click of the k into the v sound with nothing else between them. This letter combo exists fairly commonly in Norwegian so if you really want to speak the language you'll have to master what is really a simple sound, once your linguistic expectations are suitably modified.
I used to live in Southeast Alaska and had many dealings with the Tlinget and other native peoples there. It took a while but I figured out how to pronounce their words. Pronouncing Norwegian is actually very easy in comparison.
Well, if queen was pronounced with a v instead of an u that is approaching the sound. There's the hockey player Henrik Lundqvist, see if you can find someone pronouncing his name. There's also the comic "Hägar the Horrible" with his pet duck Kvak. The difficulty is going to be getting it into your head as a single sound, no matter how you think of it.
The rs are trilled, so they only sound like a d. If you know how to roll your tongue (like some kids when making motor noises) then it's simple. If not then you will need to work on that, and I have no immediate suggestions that will work for both you and everybody else who may come after you.
Correct IPA pronunciation is
/kʋɪnəɾ/ and the last sound is an alveolar flap ɾ, not a trill, and definitely not the voiced alveolar stop "d".
On the discussion page, click the word of interest to isolate it from the rest of the sentence (Duolingo will take you to the dictionary page) and hear only its sounds being pronounced.

Y'all is only used in American English, primarily the Southern variant.
Yous/youse is mostly used in Irish English, it also exists in Scottish English, and other areas with historical Irish/Scottish immigration (Oz, NZ, parts of Canada).
Note that ye which derives from correct (i.e. not colloquial) Middle English is also still used in Irish English and some English proper (England) dialects.
