May I have a little help here...
For the first paragraph:
Why some verbs have normal past tense -di, while others have rivayat suffix -miş?
Is it because some of them are facts and the others quoted?

Ofcourse according to my understanding I solved the second paragraph Hopefully I haven´t done a disatster nor distroyed the language.

Thanks

merhabalar... just a humble try to help about the question...

The Indefinite Past Tense (-mış, muş suffixes at the end of the verbs) is used whenever the speaker has not been an eyewitness to the past events. It is also often used in telling jokes as the content of the joke is just a story. So, in story-telling we use this indefinite tense  

i m not sure if i told you something you already dont know
