Jarvee Proxy Help Beginner

It’s my 2nd day using Jarvee, I have been testing it, reading online, and stuff like that.
Now I’m having some concerns about proxies, I’m hearing everywhere about 4G proxies, how many accounts can you run on a 4G proxy for Follow/Unfollow IG?(saw an old post online about running 15-20 accounts per 4G proxy but it was a 2019 one) Or is there another kind of proxy that I can use for only one account?
Thanks in advance.
