ML, SML and the Queen for sure. The FL's bodyguard is willing to put his life on the line for her but later its implied that he has a budding romance with someone else. It's unclear if he ever had feelings for the FL. 

The ML, SML, and a female character fall for the FL. 

Mainly the ML and SML. Very little time is spent on the FL's ex-fiancee. She also gains fans.

It's... complicated.

The ML's brother falls for the woman whose body the FL's soul resides in. He tries to force her to marry him and to act like the woman she was before the FL's soul entered her body (yikes this is hard to explain). The ML from season 1 fell for a an alternate timeline version of the FL. When he finds her in the new timeline, he considers her the same woman he fell in love with, even though in this new timeline she hasn't met him yet. They both time travel to an alternate version of the past where an alternate past version of the ML also falls for the FL. 

Sort of. The ML is legit. The SML is actually in love with the FL's twin sister. The FL also has a delusional stalker. 

One secondary male character in elementary / high school, one secondary male character in university, and the ML

To an extent... 

Several men in the FL's village fawn over her. One proposes marriage. The FL has zero interest in them.

Later, another man (an officer / forge owner) proposes marriage. The FL eventually accepts, but does not love him.

The ML previously didn't believe in marriage, but ends up wanting to marry the FL.
