Bearings should have no play. I've run bearings with some play for a while before replacing them but I kept a close eye on them so I did not end up with disaster like the one with the broken flange. Since you likely don't know anything about the age of these bearings you might want to replace all the bad ones. Inner bearings last a lot longer than the outer bearings. I've pulled the motor / tranny assembly out when I replaced front axle bearings however I have access to a good lift to do it with. It makes it much easier to get at them and gave me a chance to clean everything up good while I was at it.
I don't have an opinion on the aftermarket bearings. These bearings are not common so finding them at bearing dealers can be tricky so sticking with a Argo dealer is likely your best option. I looked and there were not RHP 1025 - 1 1/4" bearings on ebay at the moment and I don't know the NTN part #.
