The Q paramater in Gmail searching works exactly like searching in the Gmail website so if you go to gmail and click on the arrow to the right in the search box. Up will pop the search builder

You can play around in this and bring up any type of search you want

from:(Test@gmail.com) to:(me@gmail.com)

You can then take this and dump it directly into the q in your request

results = service.users().messages().list(userId='me', q='from:(Test@gmail.com) to:(me@gmail.com)',labelIds = ['INBOX']).execute()

Now all that being said i played around it and i was unable to get it to return emails by two different users if you put in two email addresses it only returns emails where they both where in the field. So the only way i think you are going to be able to find the first email sent to you by two diffrent users would be to do

results = service.users().messages().list(userId='me', q='from:(user1@gmail.com) to:(me@gmail.com)',labelIds = ['INBOX']).execute()
results = service.users().messages().list(userId='me', q='from:(user2@gmail.com) to:(me@gmail.com)',labelIds = ['INBOX']).execute()
