It looks to me like the first break is that your CA hinges have pulled out of the rudder. If that's the case then it's a really easy fix. All you need to do is to cut new slots in the fin and the rudder, and glue new CA hinges into them.

Break #2 looks like a stress break across the stabiliser. I think your best bet here would be to take off the covering from the stabilizer so that you can see exactly how bad the fracture is. If it's only partially fractured then you may be able to just re-join the wood with some CA. If it's completely broken but a clean break then you could glue the breaks and then add some balsa or basswood bracing to help keep them rigid. If it's fractured into multiple pieces then it might be your best bet to draw out the internal structure of the stabiliser to scale on a piece of paper and then build a new one (it's not very difficult to do if you have basic building skills.)

Break #3 looks like one of the fuselage cheeks has fractured. Best bet would be to strip off the covering from the inside and outside of this area and epoxy an 1/8" ply brace onto the back of the break being sure to keep the cheek alignment straight. Once the epoxy has cured re-cover and fuel-proof the inside.

Break #4 looks like a simple tear in the covering. If that's the case then trim off the loose bits and just iron on a patch of Monokote (or whatever your favorite covering material is) over the top.

Break #5 looks to be so severe that it's disappeared from the drawing

Break #6 is exactly the same process as for break #4.

Good luck with the repairs!
