Whenever speaker meaning differs from word meaning you have metaphor. The speaker does not really mean that anyone climbed into Jem's skin, for example, because that's impossible. Neither could anyone walk around while inside of someone else's skin. So that's a metaphor. The same reasoning applies to displaying one's life history.

"skin" is presumably a metaphor for "inner personality" or something similar, with the whole thing meaning something like "get inside Jem's personality" or "understand what it's like to be Jem".

As far as the second is concerned, more context is needed. It's hard to tell what it's describing and in what way it might be non-literal.

I am inclined to think "skin" is representing Jem's circumstances. Much like when we say walking a mile in someone's shoes.

Unless, your class is discussing Hannibal Lector.
even though i'm sure you don't need this info anymore, i decided to post it for other people who might be interested.
"climb into Jem's skin and walk around in it":
So the initial metaphor is A PERSON IS A CONTAINER, that's why you can get into it and see what's trere inside.
"putting his life's history on display for the edification of the neighborhood":
i'm not sure about this one, but i think here we have a metophor LIFE IS A BOOK, by the way a very popular one (e.g. "i've turned another page of my life"), which may be put on a display for everyone to read
