Dialogue: we can tell how the character talks (like rude language, good language)
Actions: we can tell how the character acts
Thoughts: we know what the character thinks
Interaction with others: we know how the character interacts with other people
Opinions of other: we know what this character thinks about others
I would say all of them except opinions on others. Like, you can be a nice person and think negatively about someone (well that's me).
In F. Scott Fitzgerald's novel The Great Gatsby, Nick Carraway feels that Daisy and Gatsby's relation will most certainly end poorly. Nick believes that the couple's relationship is structured upon illusion, at least on the part of Gatsby. Nick believes that Gatsby is attempting, through his relationship with Daisy, to relive the past in order to create a new future. Furthermore, Nick feels that Daisy's affections for Gatsby is owed not to any sort of true, emotional love, but rather an attraction to his wealth.
