Your question isn't very clear to me! So, I'm going ro make some assumptions:
My assumtion is that your stated rates are "Effective Annual Rates" and you want the equivalent " Nominal Rates" or what you call "APR or stated rate". That out of the way, then we have:
1)EAR of 12.3% comp. semi-annually =11.94% APR, or Nominal Annual Rate.
2)EAR of 13.2% comp. monthly =12.46% APR, or Nominal Annual Rate.
3)EAR of 10.9% comp. weekly =10.36% APR, or Nominal Annual Rate.
4)EAR of 14.6% comp. continuously=13.63% APR, or Nominal Annual Rate.
