Is it safe to get all my vaccinations again if i have no recorded shot records. and im unable to get any records of them?

Yes: There is a catch up schedule used in such cases that will exclude some vaccines for problems not seen after childhood. The vaccines themselves are safe when used as recommended. We do see an increase in transient joint pain for some adults with the MMR.

Yes: However, you could get titers, which means they could measure your antibody levels for the different organisms in question to prove that you had the vaccine before and you are still protected. That may save you some shots

Absolutely: Definitely better than taking the risk of being unprotected. I would only get antibody levels for diseases that I may already have had and therefore would need to get a vaccine ( i.e. Chickenpox) or under circumstances that you may not have protective antibody levels (i.e.- Hepatitis B)
