Yes, you have used these prepositions correctly. In fact, they are very good examples. However, you should have made two separate sentences because these two clauses do not connect in an obvious way. This is why we didn't understand what you meant.

In future, please tell us what you are trying to practise in post 1. This will save time and help us give useful answers.
