Hi, Although I am not a teacher, I can tell you that I think you have 1 and 9 correct. I am not sure about sentence 5.
Here are some hints:
In sentence 3 Suzanne does four separate things
In sentences 2 and 4 you have one out of two commas correct
Sentences 7 and 8 - always put a comma between the City and State and between the County and State
Sentences 6 and 10 - put the comma where you would naturally pause when you read the sentence
