Four of the men have confirmed haplogroups, meaning they had some SNP tests done. One appears to have done the Big Y test and their haplogroup is R-BY16590. The 3 others have confirmed haplogroups consistent with that result.
You might contact the Ward group administrators and ask them to reach out to the Big Y tester to ask if he would be willing to work with you.
