Sometimes it’s Galaxies, sometimes an iPhone called ”iPhone”. I live in an apartment building so it’s probably my neighbors.
Can I stop people from connecting to it?
Should I be worried?

You’re seeing nearby Bluetooth devices. Nothing is connecting to your iPad.
Precisely where in iPad settings do you see these devices listed as "connected"?
Consider posting a screenshot - suitably redacted if necessary, using markup tools, to obscure any personal or sensitive information - as this will help contributors to better understand what you are seeing:

You can post your screenshot using the image button seen at the bottom of the message editor:
Perhaps you have a WiFi+Cellular model iPad - and you have added a cellular plan? If so, and you have enabled the iPad's hotspot feature (that shares the cellular data connection), disable the hotspot.
You'll find information about using your iPad's hotspot feature within the iPad User Guide:
