Welcome to YT.
Since your pup was vaccinated at an older age, you probably don't need to do as many rounds. In fact, one or two COULD be enough but you would need to know exactly when they were given and your vet would have to be comfortable with this schedule. Your vet will probably end up starting over and giving a round every three weeks for nine weeks. That might be the way to go in this case. Have you talked to your vet about it?
Be careful about giving lepto. It isn't necessary in most areas and can be very dangerous for Yorkies. Also, rabies really shouldn't be given at the time of any other vaccines and combo shots at all are questionable.
