Welcome back.  As you know, your risk for infection from your condom protected exposures and receipt of masturbation was effectively no risk.  that said, many persons in your circumstance seek the reassurance that testing provides. 

When you mention your HIV test you indicate an "HIV na test".  Was this a nucleic acid test, an RNA test, or a DNA test.  I ask not because it makes a difference to interpretation of your results but just to be sure I am clear on how you were tested.  Irrespective, your test results are completely conclusive, proving that you were not infected with HIV att eh encounter you have described.  Further testing is not needed and would be a waste of time and money.

HIV-2 is not a concern.  The infection is quite rare outside of West Africa and current tests test for both HIV-1 and HIV-2.

At 30 days the vast majority (>90%) of syphilis and hepatitis C infections would be detected.  When you combine this with the low probability that you were infected, there is no realistic need for further testing.  If your anxiety forces you to test when the testing period is 100% sure then test again at 3 months.  Also, FYI, for all practical purposes, hepatitis C is sexually transmitted almost exclusively through receipt of rectal sex.
