Spot colour on Psd in mock up image and print in Indesign. HELP PLEASE !!!

Your image shows all channels checked.

Uncheck all except one, then work your way through and show only one channel at a time. Do the cyan, magenta, yellow, and black plates show in the object you assign to a spot color? When you uncheck the spot color, does the image disappear? 

As was said, though, skip the PDF and just place the PSD into InDesign.

Vector based apps such as InDesign and Illustrator automatically "knock out" content, the object has to be set to overprint in order for underlying elements to be considered in the composite of overlapping objects.

Photoshop spot channels are different, opposite – all spot colour and other channel content is combined/overprinting by default. One has to manually make a "knockout" under the spot channel area using white so that other channel data is not included in the composite. This could be performed non-destructively using layers, or one could destructively remove the image content from the other channels. Generally a selection from the spot colour channel would be used to create the knockout and one may or may not decide to manually create some "trap" (this would depend on downstream workflow).

I have no idea what your problem is, but if you want to get a Photoshop file into InDesign, link the Photoshop file.

In an image file, all channels get mixed. So, you should see anything shining through. If it gets printed, colours will get printed one above the other. If you do not want that, you need to "delete" the colour at a certain place.
