No, one photo only per person. One thing you might consider is to use a free website service like Google Sites to create a simple web page displaying or linking to the extra photos. Then point to the web page in the Website field on the person's Contacts tab.
Somewhat simpler would be to create a document with your favorite word processor that contains all the stuff you want to share. Save it as a pdf file. Upload the pdf file to a cloud service like Google Drive. You can then link to that file as mentioned above.
