Request for looking into Trade History

I recently got back into the game after being off for a year and abit, i lent my account to a good friend (ign : Nerorn) for him to use it my pokemon for whatever he pleases and another friend who uses it simply to put money into my account as i had some mons given to her for her shop and paid back to me the amount that was sold.

I found out i am missing some pokemon and he doesn't remember which ones he took and neither do i , is it okay to see our trade history so i know where my pokemon are? or maybe i'm being delusional about the fact that im missing mons?  Here is proof of his approval :
