If you seek mandatory rules for network security, you will be disappointed. Only you know what is enough. Only you know what's actually possible for your situation and knowledge. Hopefully, those two sets overlap, but they don't have to, which would leave your LAN(s) exposed beyond your skill to secure them.<br>

That's a matter of opinion. Just remember that vlans are tagging and don't necessarily provide **any** security.<br>

Probably, but I don't know.<br>

Hopefully, you firewall all access for that subnet so they can only get to the internet. The only way to be sure is to validate that is how it works. Don't ask us.<br>

Don't assume anything. Check that it actually works that way. I suspect it doesn't.<br>

<br>
I don't know any of your network equipment's defaults. Assume the worst and check it yourself.<br>
<br>
If your wifi isn't upstream from your main router, closer to the internet, I'd be highly suspicious it can access everywhere on your subnets until proven otherwise. Learn to use nmap and scan all the networks.<br>
