when use "to " and "for" and "by" and "from" and "with"and "as". What's difference?

See a translation

To = is like "I'm going to the store"

For = is like "I will get water for you, if you want?.

By = is like " Excuse me!, I need to pass by."

From = is like " Walk from this place to over there in five seconds."

With = is like "Come with us, if you want."

As = is like "As I leave to go to the store, you can start cleaning out the refrigerator."

Putting them all in one sentences looks like this: "As" I was walking "to" the mailbox "for" a package I ordered for my sister she asked if she could come "with" me because she was waiting for important mail, so as we are walking down the street I trip my sister "by" accident and she got angry because she thought it was on purpose but I just continued walking. So we finally reach the mailbox and she sees that my package came "from" China.

That was a completely made up story but I just wanted to show you how to use all the words in a paragraph, but "to" is word expressing motion or a person/thing, "for" is used for a purpose, I even used the word in that sentence haha.
"By"Achieving or to complete an action. "From" indicating a point in time, process, event or activity. "With" accompanied by (another person or thing). "As" used to indicate that something happens during the time when something is taking place.

I hope this helps you. 😊
