Note that many of those setntences don't translate word by word into English and that's your biggest mistake that you think that if you take an english sentence and translate it word by word you will have correct sentence. This mistake is called "linguistic carbon copy" and it's pretty often for unexperience language learners whatever language their are learning.
Questions which in English start with do/does,are/is/am,has/have,will have no question word at the beginning of the sentence.
Musisz jutro wstawać wcześnie? - Do you have to get up early tommarow?
Mind that if at the end of this sentence there had been no question mark, it would has been an imperative statement:
Musisz jutro wstawać wcześnie! - You have to get up early tomarrow!
