milega nahi hai is wrong, nahi milega is correct. Here 'milna' is used in terms of availability only. ur translation is not applicable in every situation as, milna is also used in sense of meeting, getting or mixing. Word for imPossible like in mission impossible is asambhav, possible-sambhav. Else u r right everywhere ye asambhav hai(it is impossible) ye nahi ho sakta.(it is not possible) ye ho sakta hai/ye sambhav hai(it is possible) to make question is it..? Just add kya at start. This is different case, u r correct in specific condition only chai we consider as femenine so it should be milegi, but no matter even if u say milega everyone will get u. Shake hands - haat to mila ja / haat mila na its 'haath' not haat these seem to be very informal sentences n should be used with frnds n younger family members. Haath mila naa sounds as if u r very informaly requesting someone to shake hands. 'Haath milaaiye' will be good pronounce as 'mile'ga i like in bit, le like lay/say in english n ga mi-lay-gaa 'mile'gaa. There are alternates also but i would like not to increase the complicacy :)

i want to make some correction,in your following sentence... 1)it's possible --- (in hindi) yeh sambhav he or ( locally or mostly said like this) ho sakta he 2).it's not possible --(in hindi) yeh sambhav nahe he (mostly said in local) nahe ho sakta 3)is it possible ---(in hindi) kya ye sambhav he??? or kya ye ho sakta he In all these sentence,you can't use "milega" 4 .kya mujse thore se chai milege(you can also write chai milega ,it is true). 5 from where you will find....it is right sentence.. 6 shake hand......hath milao 7.not found .......nahe mila okay now pronounciation is like mi--le-ga ,and it's surely not emphasis on "e" ,it emphasis on "le",whether you say milega or milege mostly you can used this words for "get" (or even find or meet) thank you. have a nice day....
