I ordered the 5p is it good when compared to 1c which I am being offered used

Never played a chinese mass produced guitar, have you? There is much worse out there. Alhambra C range is a student guitar. If you can afford better, of course you should buy a P. But for a beginner, those top guitars sound too clear and fine. I think it’s better not to learn to play on such a good guitar, it would certainly not make things easier for the student.
