In sequence,
Yes, Samovar, any format of question and answer is okay on this forum, some questions go unanswered longer than others, but that's understood.
Orson, Unfortunately you picked 3 7-letter answers which don't intersect. The intersecting ones intersect on W and O. The other one doesn't get entered into a 7-letter entry.
Xij, RR is due to arr (for 'arranged by') substituting 'vowel' (ie O) of 'word'.
Napkin is formed for NAIN around PK. Since AR are the extra letters, I assume that put = park.
