on question 1, totally false.
2 false
3. false
4. true, if one wants it in that direction.
5. work is scalar in conservative systems (we live in a conservative universe). Force dot distance

Mystery: What text are you using? These are unusual questions for a HS text. This wording sounds very much like linear algebra.
Remember the definition of orthogonal: Two vectors are orthogonal when their dot product is zero.
