I'm pretty sure MacroDroid can run multiple loops in parallel. I can't tell what your macros do I'm afraid as I don't speak the language you have posted in. You may get more response if you switch to English and re-post the screenshots and describe exactly what you see.
If you are losing accessibility then please check dontkillmyapp.com. Unfortunately this is caused by the OS and not something I can resolve in MacroDroid directly.
