I want to know what to do with a young bunny with a swollen right leg that looks like to either has fluids or cancer on his leg... then I have another one with a swollen face

It's hard to tell from the photo if that is a swollen leg or a lump such as a swollen lymph node. Certainly, it needs to be examined and the vet may xray it or pop a needle in to see what is inside (checking for e.g. pus or fluid).

Hello! My rabbit has a huge and swollen wound in his mouth, the veterinarian said that it isn't an abscess. She drank his teeth and gave us treatment with antibiotic. We have a record time with the vet for a check-up on the coming Monday. The treatment went well, but the rabbit didn't want to move. I noticed he did not want to step on his right foot (the wound in his mouth is also on the right). The chin is still swollen and the neck very tight.We give Еnrofloxacin in the evening, but we don't know whether because of it in the morning the rabbit doesn't want to drink and eat. Do we have time to wait until Monday? Can you give us first aid advice at the rabbit's foot? Kind Regards! Mirena Hristova

Without examining Gosho I cannot say what specific injury he has with his foot, but you should keep him rested for the time being and don’t encourage movement; if he isn’t eating or drinking try to give at least some water by a dropper or syringe drop by drop to see if he will drink.
