I read some where that dajjal will rise from the khurusan, from the jews of isfahan? Is this true??

And if that's the case, then won't Imam Mahdi (A.S) be rising from the khurasan too?

I haven’t read any such thing in the riwayat

Imam Mahdi (AJF) will rise from Mecca. You can refer to volume 52 of Bihar for details.
