The wording of the question is kind of weird, so we need to ask questions about the past basically.
1. What did you do yesturday? (this one was free)
2. How many of your paintings have you put on the cd?
3. What did you do with the rest?
4. How have you put them on the computer?
etc
Just make sure to ask questions about the past, they don't ask you to specify if it's past simple or present perfect so anything will do you don't even need to know.
For question 6...
1. What have you done today? <- not sure what they wanted from this question.....
2. worked, searched <- past simple
3. Did you find <- present perfect
etc
What part did you have trouble with exactly? I'm not going to do it all for you but I can explain parts
