Problem with copy-pasting the head/object for a character

hi im a student and im having problems with trying to copy+paste a head into one frame. My problems are : it doesnt paste onto the one frame or it gets pasted but its in a weird angle. like in the image attached.

ive tried copy + pasting it from the master-peg but it results into that. tried it from the camera view and it doesnt work as well. ive tried the paste special but i cant understand it very well.

thanks for the help
