Personalmente, prefiero "Mis maestras están muy bien" a "Mis maestras son muy buenas", porque lo segundo se puede confundir con el sentido moral/ético. Aunque prefiero cualquiera de las dos a "Mis maestras están muy buenas"
Spoiler :
Personally, I prefer "My teachers are very good/My teachers are very well" to "My teachers are very good/My teachers are very good people", because the second one can be confused with the moral/ethical sense. But I prefer any of them to "My teachers are really hot"
