I'm not sure that I could get your point but if you mean, shortened and broken version of those words, my answers are as follows, おはようございます　⇒　おはざいまーす、おざまーす (I've never heard おはあり before.) お疲れさまでした　⇒　おつかれしたー　 We don't say おす instead of お疲れさまでした。 おす／押忍 means yes, yes sir! Basically, this word is used by student or trainee at martial arts (Judo, Karate and more) or other (school) sports training situation.
