Reply to comment by Maplelongjohn in How can I add a second 1/4 inch water line to under my kitchen sink? by Apprehensive-Egg374
Here are some better pictures of the pIpes:
Do you have more specific advice based on these pictures? Like does the pipe need to be removed? Or is it fine as is? If it should be replaced, what do you think I should use to replace it with?

What I would do
Wait til Monday because an emergency plumber on the weekend cost 2x.
Shut off water
Drain system
Careful remove those valves. Unscrew the flex lines. Remove everything coming up from the old valves. Make sure to use 2 wrenches to counter hold the fixture so you don't accidentally snap anything off.
Remove the old valves holding the pipe coming out of the wall. Hopefully the threads stay on the pipe .
If that all comes apart without incident you've pretty much done it.
You need to verify the size of the pipe from the wall- is it 1/2 or 3/8" NPT (national pipe thread)
Find new quarter turn stops that fit that pipe(1/2 FPT(female pipe thread) x 3/8 compression is common)
You can find bullhead stops as well, so each fixture has a valve. 1/2 NPT x 3/8comp x 3/8 comp for dishwasher and likely one with a 3/8 & 1/4 comp for cold side.

Now that would work to get you back to where you are now,. looking for a place to connect the fridge.
You can use a compression T https://www.lowes.com/pd/Dial-Brass-Evaporative-Cooler-Water-Hook-Up-Kit/3092871
But I'd use 1/4" copper tubing to connect that tee to the stop.
Then you'll have 2 @1/4 compression and one 3/8 compression fitting for sink, water filter and fridge.
The hot side you'll have 2 @ 3/8 for the faucet and the dishwasher

Thank you so so much!! That was very detailed and helpful!! I really appreciate it!
In case the pipe thread does come off, what would I do? I don’t have access to the other side of the pipe as it’s behind the wall…Would there be a way to fix it with an adaptor or something?
One more question if you don’t mind: Do you think it would be possible to setup a washing machine to get hot/cold water and drain to under the kitchen sink?

Sometimes the pipe threads/ end of pipe can be removed with an easy out, if not that's where the plumber and a repipe comes into play.
Likely need to open the wall. What's on the other side of this wall?
Negative on that laundry.
But if you have a plumber come they can assess the situation and make recommendations.

The other side of the wall is another apartments bedroom. I live in an apartment building (I own my unit). Thats somewhat the issue. If the pipe threads come off, the other pipe thread is far behind the wall and I’d have the break the wall. And it’s possible the next pipe behind the wall also breaks off when you try take that pipe off lol so it can be endless. The building is very old and so I’m sure the piping is very old as well. Is there a way that if the threads come off, I could cut the pipe to make the ends straight, and then attach some type of adapter or something? Or the only way is really to keep removing pipes behind the wall till you get a thread?

I imagine you can't even shut off your own unit without the whole building and thusly that assembly of stops and fittings you have there ...
I'd just add another add a t for the fridge and be done with it
Or get ready for a barely reasonable to quite large plumbers bill...
Chicago? I'd guess from the brass drain assembly.
Get an outlet cover on the electric, no reason for that.

The super can close my apartments water. I’m in NY.
If the brass pipe coming from the wall brakes off, can I cut it and then deburr it, and then use this shark bite attachment?

Now if anything goes wrong what your concerned about is the 2 pipes coming out of the walls.
These are probably corroded and mostly clogged up. The threads might stay in the valves when you go to remove it.
You may be able to unthread the pipe from the wall and replace that.
The pipe may snap off inside the wall as soon as you touch anything, and necessitate opening the wall and running new pipe to the sink.

So I’m in an apartment (I own it) and I don’t have access to behind the walls. And the end of the pipe is behind the walls. So if when I try to take off the shutter valve, the pipe cracks, or the threads for the pipe comes off with the shutter valve, the other end of the pipe is far behind the wall and I don’t have access to it to replace the whole pipe. Would there be a way to solve this issue in case it happens without removing the wall to change the pipe? Like is there an adaptor or something that I can use to attach to the pipe if it breaks off to give me a threaded end to use?

You'd be opening the wall through the back of the cabinet then.
It's probably worth every penny to have a plumber come deal with this.
They know all the tricks to help prevent the worst case.
They have insurance too. In case the worst happens and you flood the neighbors.
