I need to add a pic to another pic

We can provide advice on how to do this. 

Doing the work for you is not exactly what this Forum is for, though someone else may have the inclination and time to do so anyway. 

Please post the two images (or at least lores-versions). 

The Object Selection Tool’s »Select people« may provide »good enough« masks (though manual improvements may be called for) to clip persons from one image. 

When inserting them in the other image converting them to Smart Objects provides the advantage that repeated transformations (scaling, rotating, …) will not degrade them unnecessarily.
