I Don't Know Why I Keep Buying These!

I don't know whether I can ever solve these

I haven't bought any twisty puzzles in many months and decided to catch up with a few that had gone by. I have bought these:

Gemini 4-Corner Magic Cube
Lanlan X Cube
Clover Pyraminx Cube
Fission Skewb Cube
DodeRhombus
Crazy DodeRhombus 

The two at the back scare me to death! First I need to sticker them and then I really doubt I can solve any of them.
