when I use my phone as a hot spot am using up data and if so how fast will I use it up? they just switched me from 10 to only 4 now.
It all depends on what you are doing to use the data.
More devices connected means more data. If you have a PC running off of your hotspot, thats even more data than a phone or tablet. With only 4GB, I would pay close attention and use tight reservation on activating the hotspot very often.
