Hi Jadaku,
welcome to the Apple (user-to-user) Community.
Re: "Email replies on iPhone comes to me, not the sender".
Wondering which iOS version you have installed on your iPhone: Updating may help:
Eg: About iOS 16 Updates - Apple Support says iOS16.5 is the latest version
If you have already updated to iOS16.5, you might want to try restarting your iPhone.
Restarting will often clear the way, or restore order if something is not working right.

If you still need help with the issue of eMail replies:
Wondering if you are using the "Mail" app, or a third-party (non-Apple app).
Eg: For Mail: You could check in Settings > Mail to see if anything needs changing:
You could also check your "Contacts" app to make sure the people you eMail are listed there correctly (and are not blocked)
(You may have a setting in place that only people in your contacts can contact you.)
For a third-party (non-Apple) Mail app: You may need to check with the provider.
Trouble-shooting: If needed:
Eg: You could try removing your email account, and setting it up again
If you can’t send email on your iPhone or iPad - Apple Support

You might want to reach out to the Mail Support:
There is a "Get Support" link (online chat, phone, eMail etc) (or an app) at the bottom of their webpage (link below)

All the best :-)
