SusanSusan your #2 blocks look great! I've only made one of #1, one of #2, 40 of #3, one each of #4 (both blocks) and none so far of #5. I, too, had a bugger of a time with the 45 degree angle! Hopefully, I will get the hang of it when I make some more of them.
I love your choice of fabrics, too!
If you're not happy with the way your points meet, shuffle your blocks around. Some may fit together better than others. Just a thought...
