Want to preface this by saying just started reading this series yesterday
As for yunos grimoires it's a 4 clover with wind magic. In the series there's 4 basic basic elements where all others suppose to be derived from. I think the other 3 kingdoms will have people with other 3 basic element grimoires of fire water earth. I think symbolically yunos is wind is clover are associated with color green which is associated with wind.
Asta on other hand has a demon grimoire as 4 clover is associated with fortune the 5 clover is associated with demons most likely due to the penragram. It seems both yuno and asta have a yin yang relationship like Naruto and sasuke. While yunos path is filled with good fortune you could say asta is cursed with only hardship keep coming his way.
Asta is thought to be associated with the demon asteroth in life he belongs to a demon trinity with Lucifer and beelzebub so there might be other demon book users.
