Vibe check on these more unusual boys' names please

[LimeslemonsPomegranates]

I would like to vibe check these names. Many of them are more unusual so they probably have a stronger mental image or stereotype attached than names used more widely. What do you imagine boys with these names to be like?

Cosmo
Edmund
Hector
Conrad
Magnus
Lysander
Rafe
Ranulph
Peregrine
Benedict
Leonidas

It sounds different (and nicer) in Swedish though.
