What are the differences between all the conditional in japanese ?

I know that と is used for logical condition (if I drop the ball, it will fall) but what about えば/たら/なら?

If you have some simple examples please.

Hi. I guess your question could be answered by master of Japanese grammar haha. Moreover most of us doesn’t know the differences between all the conditional in Japanese.
You know, Japanese is very flexible. So it’s difficult to understand it in regular patterns. Therefore I think you should get used to various conditional in real sentences.

If you get your hands off the ball, it will fall.
ボールから手を(離せば/離したら/離したなら)、(それは)落ちます。You can use all expressions.

If you get there, you will understand what I’m saying.
(行けば/行ったら/行ったなら)、わかるよ。

〜すれば=〜したら>〜したなら

If you speak about unrealistic things, I think you should add “もし“ or “仮に” at first☝️
If I were you, I won’t do that.
(もし/仮に)自分だったら、やらない。

I’m sorry that I couldn’t answer your question. This is my one of suggestions. Good luck!
