1. Tonight I go in the language school.
2. At 8 pm I meet him in the cafe.
3. Not sure how to make a sentence with this one.
4.Mrs. Stein buys fruits and vegetables, in the health food store. ( or you could say it like this In the health food store, Mrs. Stein buys fruits and vegetables.)
5. Mr. Schulz drinks beer in the pub.
6. You can find ties in 3rd floor? I think this might be it.
7. I want to go in and dance the disco.
8. ? not sure.
This should help you except for 3, 8, and possibly 6.
The question seems a bit incomplete but I believe the correct answer should be 2. was not.
That would correctly complete the sentence like so:
I was not there when the crime happened, I only heard about it afterwards.

Mein Freund mag Krimis.
Der Kaffee gefällt meiner Schwester nicht; er ist zu süß.
