N/A

They unfortunately can't, only way to do that would be to host them on seperate accounts

I am trying to create a separate account but it says my Github account it is already connected to another Railway account so I can't get verified…

yea, github and railway only allows for a one to one connection with each other
maybe you can create an orginization in github and connect your other accounts to that org?

I'm not sure if this will work, but it's worth a shot

I see. I actually have an organization on this account.

is there any workaround?

not that I know of, apologies <:PensiveFluent:865332812042731539>

Is there any way you can escalate my case, or something similar?

You can speak to the Railway team directly if you're on pro plan, but on hobby plan you're limited to community support ( which is this help forum )
you can definitally share your feedback regarding this in <#1157406325593096264> though if you're interested in that
