I bought a house a few months ago and I’m still trying to figure out all the wiring. I found these coming out of a cabinet in the kitchen.
I think (?) the black one is a cut-off coax cable. There’s a LOT of coax in this house, so that seems straightforward (but I would still love if someone can confirm!)
I’m not sure about the other ones. They don’t look electric, as I’d expect electric to be black + white + copper, like the rest of the house.
There is supposedly a speaker system in the house (I see speakers) but I haven’t figured it out yet. Could that be power for the speakers? I’m not familiar with speaker wire setup. If it’s speakers, why would there be so many wires?
Do you have a chicken stick yet? Every homeowner needs a chicken stick:

Like others have said, it’s speaker wires. That’s not what you’d used for electrical wiring. Nothing wrong with being cautious and checking for voltage with a multimeter, but those are most likely speaker wires.
The reason there are probably so many wires is they may have had a stereo receiver located there for patio audio or something similar with a cable box as one of the inputs on the receiver.
You might look into buying a tone and probe kit if you are having trouble locating the wires. A toner runs an audio tone through the wires and the probe wand has a speaker that helps you hear and follow the sound that runs down the wire.
Those look like a cable TV wire (the coax) and speaker wires. Get a non-contact volt sniffer (NOT a multimeter) to check for the presence of voltage in these before touching the conductors, but it looks like entertainment wiring to me. IMHO - I’m not a licensed electrician, so take this interpretation with a grain of salt.
Left most looks like cat5/6 Ethernet cable but hard to tell from pic. If there’s multiple tiny, colored wires, solid and a striped, it’s that. Next one is RG-59 coax. Others look like speaker wire of some sort but I’d test with a multimeter to be sure they aren’t live
Edit: RG-6 to RG-59. Hard to tell from pic though
Looks like it could be speaker wire for stereo, left/right channels
Is there another end or are there speakers in the ceiling or walls?
Do you have a volt meter? You can use that to match the ends, twist one set together and see which one is closed.
If that was connected to a wall jacks, someone is an asshole for not leaving it. The part tools to strip and rebuild the connectors aren’t expensive but they a one and done tool for a diy-er. Maybe you know someone that can borrow you the tool.
These days, there are a lot of wireless options so you could also shove it the wall and buy a blank plate to cover it.
