It's generally fine to do this. Other users in the past have done the same thing. If you don't abuse it (like bombard the site with 20+ questions all in rapid succession) it's typically fine. Six questions isn't really an issue. The only thing it really does is skew the main questions page some since it'll have your questions all listed as the newest ones until someone else posts something, which really isn't all that long.
This reminds me of performing edits in a rapid fashion. In the past, users have made lots of edits to posts very quickly, causing the active questions tab to get updated with all the posts that were edited by said user(s). I am guilty of doing this myself a long time ago to the point where I received a warning from the mods (this was well before my time as a mod myself)!
So let's leave it at this:
- It's fine to post questions like this, so long as it's not an extreme amount.
- Keep in mind what it does to the questions page.
- Try not to do this multiple times a day, and maybe consider spreading some of them out, or asking your question when it first comes to your mind instead!
