OK are you asking how to set up to run your PC and Laptop to access the internet via your phones data (using the phone as a hotspot) for the other devices? If that is the case, first let me say that your phone uses a lot less data than a PC and Laptop, and it is possible that your carrier has limits on the data usage, or even limitations on using the phone you have as a hot spot. Some phone just can't as well.
However, if that is what you are asking, it can be done, you just will probably wind up with a huge data bill or your data restricted. Even so called unlimited plans usually have data caps.
Or, are you asking about running them all through just a WiFi connection (not coming from the phone)?
