We must use 'simple future tense' when talk about 'promise, sure, think, probably'.
-I promise I will buy you this toy.
-I feel a bit hungry. I think I'll have something to eat.
-I’m sure they’ll help me.
But I have seen they are used with 'Be Going To'.
-I am not sure how I am going to handle it, to be honest, and I will just be sitting there.
-I think I am going to go back to the way I was before.
What is the difference in there? Why must we use simple future or other while using verb such as 'think, promise, sure'?

That's a little over-simplified.The general rule between forms (will/going to) is that "will" for spontaneous statements and "going to" for planned actions. Google for more detail/exceptions.
There is no need to google. UsingEnglish.com has a series of articles on grammar topics, including Ways of Expressing the Future in English.
Incidentally, as the article explains, there is no future tense in English. The construction with 'will + infinitive' is simply one of several ways of expressing the future.
-Each time I board a plane, I believe that I am going to die.
I think I is ok. Is that right?
It's grammatically fine.
