Adorable puppy! I think he looks great!
While I am by no means an expert I do have some comments on your play date.
First, they are suppose to be fun, happy experiences for the puppy. It sounds like your poor puppy didn't get to have much fun. I would look for other doggie friends to play with so that your puppy will get to have a good socialization experience.
Second, I would not put another dog in my puppies crate, especially one that has been trying to bite my puppy. That is their special place. When the chihuahua was in the kennel Lincoln was probably sitting there thinking "hey, that's my room! You aren't suppose to be in there! Get out! Now it is going to smell funny!" If you do have the dogs come over again, have the owner bring her own kennel so everyone can retreat to their own safe space if needed.
Again, I'm not expert, just my thoughts. And again, super adorable little guy!!
