Question

May you help me get these answers please​

Answer 1

Your doing great so far. #6&7 are correct. For number 8, it is usually Karen and I instead of me and Karen.
The sentence with #9 & 10 would make more sense if it went “on Saturday, us and them ...”

#11 would become we so that the words “Karen and i” don’t become repetitive.

#12 is correct

#13 becomes us.

#14 becomes We

and lastly #15 become us.

I hope this helps:)
