The second author of this and his other articles is not Bakhodir Khusanov. The author of these articles is Bakhtiyar Ergashbayevich Khusanov. How can I fix this?
This is a frequent problem in ResearchGate in case of similar or identical names, in most cases caused by an automatic algorithm of RG. See "Another researcher has claimed my publications" in https://explore.researchgate.net/display/support/Authorship for instructions how to correct this. But unlike this help page suggests, most probably it was not the other author himself who wrongly claimed authorship, but ResearchGate's automatic algorithm wrongly identified him as the author and assigned your publication to his profile.
