It's spelled "ven", and yes it means friend in Danish.
god venn = good friend
elskede = beloved "min elskede ven" = my loved /beloved friend
Literally: "Little/small friend" - it must not be mistaken for an insult, it is a way of expressing affection. It is a common way of adressing a close friend.
Friend: Venn. Friends: Venner.
"Farvel, kjære venn"
Take lessons in it, or find a Danish friend, who you can learn it from.
It is not a danish word.
"Tusen takk kjære venn" means "thank you dear friend". It's a statement, not a question, and doesn't have a general answer or response.
If you mean; what is the danish word for he and she, it is: he = han she = hun
"Ja" means 'yes' in Danish.
If you mean the danish currency we have our own, the danish Crown (DKR(Danmarks krone))
Jeg savner deg, vennen min. ;.(
