Question on IP device max. and IP address

Sup everyone,

I'm currently running 5 accounts from my iPhone. I log into each one several times a day from the same device but from different wifi connections (home and office mostly). To avoid confusion, yes, I log into each one of the accounts from each wifi network.

Is it safe to, let's say, create 5 additional accounts from another device and run them on the same wifi network?

So for example, can I run 5 accounts from one device and 5 accounts from another device, all devices being connected to my wifi at home?

Yes, I'm a noob and know nothing about IP addresses and how that stuff works I am learning...

Yes that's totally fine so long as IG hasn't blacklisted one of your IP's in your network.
