Hi everyone!
I'm learning Portuguese in an app (Duolingo).
On my app, I started what they called the preposition part.

And I'm so confused. There's no vocabulary list and most important: there's no explanations. So now, I made my list of words which all looks like each other and I can't even make a difference between them, I'm using it completely randomly.

I hope you could help me understand the difference between them and maybe show me some examples of using them.
Do not hesitate to tell me if, in my list, there's some of them you don't use (or not often).

Here's my list (I might have forgot one or two), alphabetically:
- àquele / àquela
- daquele / daquela
- dele / dela
- desse / dessa
- deste / desta
- disso
- (disto: if "nisto" exist, does "disto" exist? I don't remember seeing this one)
- naquele / naquela
- nele / nela
- nesse / nessa
- neste / nesta
- nisso
- nisto
- no / na

Please, can you help me?
I know I'm asking a lot in only one question, but I'm completely lost...
