Hello Sergey! In the first sentences, we would definitely say "..., but I got used to it." In the second: "5pm would be suitable for me." But most people would say "5pm works for me" in everyday speech."

To be used to something means to be accustomed to something. -To get used to something means to become accustomed to something. -'Used to' is followed either by a noun or by a verb ending in -ing. * noun : I am used to noise. I am used to hard work. * verb : I am used to living in a noisy street. I am used to working hard. ** 'Used to' refers to something that was strange before, and has become familiar, something that you have learned to accept. ** It is used with the verbs BE and GET in all tenses: past, present, future & conditional. - Now that I live in France, I am used to driving on the right. - Since I moved to the city, I have got used to noise. - Before I came to France, I wasn't used to drinking wine. - This computer is new. I'm not used to it. I will get used to it soon. - I wasn't used to the weather. It took me some time to get used to it. Get used and would be suitable are more commonly used in daily expressions. Hope that helped!
