Not sure about the mucus. That could be a number of things. The yellow liquid that he is throwing up is probably bile acid from his stomach being empty. Try some scrambled eggs to help his tummy.
A 5 month old puppy can not go without eating for long. The important thing is to get something in him. If he is throwing up then he could become dehydrated. Try to get some Pedialyte in him as well. If he is not eating only because he wants table scraps then you may need to comprise for a bit. It sounds like you are only giving him dry food. Try mixing the dry food with some wet food. I would try Merricks Turducken. It has reals chunks of chicken and turkey and smells just like people food. You might be able to fool him!
Hope he gets better soon!
