If it stands for a while it doesn't make the sound at first. But after focusing 3-4 times the sounds come back. If it would have been a mechanic issue wouldn't it make the sound Every time then?

It sounds like one of the internal bits has bent just a little bit. There is also some play in the connection of the moving parts, so sometimes things scrape and sometimes not.
Did you get a drop of oil under the RF cam follower arm? If so, and it's still doing it, the top will need to be pulled to get at the components making the noise.

It is very hard to get lubricant to the bearing of the rangefinder, "from the outside". My first bet is that the shaft and bearing for the focusing arm needs lubricant.
See:
The shaft at the bottom is where the focus arm attaches. The bearing is at the bottom of the rangefinder, and NOT in the body shell casting. That bearing would be where my first point of investigation would be, for a squeak
And the spring and mechanism beside the big VF prism is where the mask and parallax compensation mechanism is. It can squeak too, if the lube is dry.

oh oh oh, here is an excellent view of the bottom of the rangefinder module, and the bearing for the focus arm
See what I mean, the bearing is on the bottom of the RF module.
And there is a sheet metal plate right beside the big VF window. It covers the sliders for moving the masks for parallax and changing the masks for different lenses. They can squeak too.
Does it squeak when you change framelines? Then the mask sliders need lube too, but you can get at most of it without removing the RF module. I've seen this mechanism get gummed up
Oh, on the M5, the meter mechanicals are ON TOP of the RF module, forcing you to take the meter parts off.

Try just the frameline lever. Does it squeak?
The frameline lever just moves the frame mask, and not the rangefinder viewing lens assembly, and also doesn't move the focus arm nor its bearing.

Good stuff Vick. I see what you mean; it looks like it would be unlikely for any oil applied to the cam follower shaft to make it to where it could do any good. Top comes off for sure. I seem to recall the flat bit to the left of the window is accessible in the M5 without meter bits in the way, so you could probably access the sliding parts if you are careful.
One needs to be very careful when working with the meter components. It is extremely easy to get them misaligned slightly when putting things back together, resulting in a disappearing metering strip below the finder image. The little sheet metal angled mirror holder on the top of the meter is fragile, and needs to be JUST SO to bring light in from the illuminating strip in the front of the camera, and you need to be putting the top on and off to adjust it correctly. And yes, of course I learned that the hard way.

The strangest thing. I have now bought a new M5 and a new Color-skopar 35 (same set up). And guess what? This one started to sqeak too. Is it the lens/camera combo or just a big coincidence?

Did it take weeks before the sound disappeared?
