Well, there isn't really. The only way would be just to re-try each of them. I'd like though to suggest you this
webpage for Stunt Jumps guidance. It shows you a video of each jump done correctly. Every single aspect such as speed you should jump with and especially the point you should land on is all covered.
However, if you happen to be on PC, I might have an option for you. I have a tool that allows me to do the Jumps much faster. It simply transports me there. Upload your save file here
and I'll try to tell you which you missed.
