The thing to do is to look for your five ideas in the existing massive long list of user wishes and, if those ideas are already there, use one of your 10 forum votes to vote for those existing ideas.
If your 5 ideas are not already there, then add them into the request voting section in five separate individual posts (not grouped together with 5 requests on one post) and see if any of your ideas get any votes from other forum member.
Two things to remember -
there are hundreds of user requests in the queue - only a fraction of them can be added. Your 5 might be the 5 most important “must have” features to your mind, but every requestor feels the same way about their requests too.
Some requests, and they are only requests, never ever happen
Spotify backed off from dj world. Recently only they came back to some dj softwares.
Rest - look in feature request area.
