As a native speaker, I've pasted what I'd answer below along with notes for each.
1) Feelings: tense; confident; confused; determined; motivated; upset
NOTE: For "feelings," this typically describes something abstract, like how something makes you feel and/or what kind of reaction it makes you have. "I feel upset when someone hits me" because you get mad if someone hits you, or "I feel confused when I do not understand something" because that confusion you feel is a direct result of not understanding something. "Tense" was a good answer as well, because you might feel "tense" if you're worried or anxious about something. I included "confident" here, which is tricky. You can "feel confident" about a specific answer, but you can also "be confident" as a person. One is a temporary thing ("I felt confident that my answer was right"), and the other is a permanent thing ("He was a very confident person").
2) People: confident; demanding; determined; motivated; practical; supportive (NOTE: Upset is a feeling, so I likely wouldn't put that here. Technically you could call someone a "confused person" as a description, but that's normally an insult so I won't include it here).
3) events: compulsory; significant; major (NOTE: Significant and major are synonyms that, in this case, mean basically the same thing - important).
4) information: relevant, practical, significant (NOTE: This is where significant/major differ, because information about a situation is largely just significant, ie important, but "major information" isn't typically right/used. This is one of those inconsistencies about English).
5) places: cosy, spacious, unfamiliar (NOTE: this one was exactly right; they are all words that can describe a place)
