The way that I found this out was that I looked at question 8 (H) and I saw that the answer was the same as the last multiple and it could be any number but the diamond would have to be one. For the second question that I answered I did question 7 (F) and the first multiple was the same as the answer so I that it would be number 0. Then I used the knowledge that I already know to solve out the rest the answers are:

Upside down triangle=0
Diamond=1
Rectangle=3
Eight sided star=9
Square=2
Oval=4
Semi circle=8
Circle=12
Triangle=6
Pentagon=5
Hexagon=10
