If you haven't worked on connecting before, there are some Hints and Tips on the Connectors Chat page.
If you can add sources, photos, or biographies, build out the family trees, or improve these profiles in any other ways, so much the better!
P.S. I'm not a WikiTree Leader, and have no authority to assign points, credit, or anything like that. My intent with these challenges is for them to be a fun little break from whatever you're doing regularly. There's no time limit, there are no prizes, and if you have fun finding and adding relatives, then you win. (And WikiTree wins in any case, because the more connected profiles we have, the better the tree is for everybody.)
That said, if you manage to connect any of the profiles listed here to the main tree, there's no reason that you can't count that connection towards the Connectors Challenge, if you're taking part in that. (Or, you could count it towards the Sourcerers Challenge if you run across an unsourced profile which is already on WikiTree and add one or more sources to it.)
P.P.S. If this challenge intrigues you, and you think you might like to try your hand at connecting other unconnected branches, you can find more threads like this on the Places to find unconnected profiles page. (Or, if you want the Reader's Digest version, check out the State of the "can you help connect" address thread.)
