Multiple Active Remote Desktop Sessions

HI all,

i have a Server 2016 standard configured with MS SQL as a DB server in my Organization.

and it has multiple incoming remote desktop request from our Developer team,

for the time being it can only use by 2 active remote desktop connections only. i need to increase this limit to minimum 5 active connections . what is the correct way and the best practice to get this done and apart from best ways.. is there a short cut and cost effective way ?
