It might help if you can tell us what the other ends of the red and blue hoses are connected to. (They look like aftermarket upgrades so color alone won't give a clue.)

I also have a '94 850 t% but unfortunately don't remember ever seeing the metal box in Pic #3.

I can't tell from your photos where those lines should be going, but this thread is a good place to start: https://www.matthewsvolvosite.com/forums ... php?t=6941

There will also be a vacuum diagram on the inside of your hood you can check and hopefully be able to trace the lines with.

Here are better pictures. Red circled the problem spots.

The red vacuum hose isnt related. Its coming from turbo and going TCV.

Tried to read that Vacuum hose diagram but doesnt help me much for those two lines (?)

Tap on air tube needs hose

Upper hose near intake manifold

Is there a vacuum diagram on the hood of your car?

Most of the lines on your car will be similar to S70 so the nipple on the air tube probably runs to the fuel pressure regulator (https://www.matthewsvolvosite.com/forums ... hp?t=63615).

But the 94 probably has EGR and CVVT manifold so there are some quirky lines near the vacuum tree, would help to see the vacuum hose diagram on your car.

The second one, at the vacuum tree, is there a hose connected right now and you want to know what to do with the other end, or there is no hose at all right now?

Found the right places. Bypass valve hose goes to intake manifold. First picture.
Tap @ intake tube gets a hose from TCV. Second pic.
My car has no EGR i think. Its European model, 2.3 litres engine. Not Usa model

What kind of Coolant fluid i should buy, which color etc?

If you are in Europe you may have more options but over here I buy Zerex G-05, it is very close to what Volvo will sell you. But a lot of people even use any old green coolant with apparent issues.
