If my period came on 1/25/2023 & end on 1/31/2023, den i had sex with someone february 5 then i had sex with someone else like the rest of february, who is most likely my baby father?

Unknown. Pregnancy has been documented from sexual activity on any day of a woman's cycle, including during menses. It would be more likely when the encounter is mid cycle, but when there is more than one possible father, it becomes a legal issue. Surprises at delivery can be quite problematic. A NIPS test on mothers blood at 8-10 weeks can be used to confirm paternity.
