So, I have had a buddy lead the way on wiring my basement of a basement finish in a home built in 2017. The builder ran two wires from the panel in the garage to facilitate the finishing of the basement. Of course, now my buddy is on vacation for 2 weeks and I'm at the point of hooking up all my receptacles (so I thought). We spliced the two wires coming in I've attached a picture of that. When testing for power in boxes, I've only got about 60% with power. I'm assuming this has to do with the way the hots are together. Is it about just playing around with them and figuring out the best match? Any insight is much appreciated.

First off, all the grounds should be joined.
Second, you should verify that both of your input cables are hot (presumably they go to different breakers - they should.)
If both input cables are hot, and are joined to your other cables, (in any array - which should not matter if all loads are 120V, so long as you keep the hots and neutrals together for each set) then not having power on some outlets is not likely to be in this box, unless you have a phenomenally bad wirenut connection here. [that's not unheard of if you have little experience using them.]
There's a bad connection or no connection somewhere, though.
