How to connect a bunch of Raspberry Pis to the Internet?

[PatrixML]

im running a Discord server, and instead of running separate instances for each of my server bots I want to get a couple of raspberry pis and load one onto each. How would I get these connected to the Internet? (If possible, not connected directly to router as only 2 ports are available)

This is what a switch is for.
However many ports you require.

Exactly, a cheap, unmanaged, 100Mb switch will do.
You can buy more expensive, managed, 1Gb switches as well, those will work too, but for your purpose, the cheapest will do the job just as well.
