It depends on what age her first vaccination was as to how many she needs.
I start at 8 weeks with DHPP or DAPP (I do not give Corona). then they get a vaccine at 12 and 16 weeks. Rabies at 20 weeks.
If your breeder did the first vaccine at 6 weeks then you will need 4 series. The last vaccine must be at 16 weeks or older to be safe.
Be sure to separate your vaccines by 4 weeks and never give rabies at the same time as the other vaccines. This also goes for lepto, lyme and any other vaccine you choose to give. separate them to avoid a reaction. Do not overload the system.
A year from the 16 week vaccine they get a booster of DP and then 4 weeks later they get a 3 year rabies.
3 years from the one year booster of DP I titer test to check immunity prior to giving any more vaccines. I titer every 3 years from there on out.
If you got your pup from a breeder, didn't they give you a schedule of when vaccines should be given? and what they already gave? They should have.
Re-reading your post it seems the breeder took the pups at 6 weeks for first vaccinations. Just be sure you separate by 4 weeks and the last one is at 16 weeks or older. You will need 4 vaccines if I am reading your post correctly.
