Most likely. If you use an STA, everything (plate, wing, STA) lines up with two 11" spaced holes down the center, so mixing brands isn't too big of a deal. However, if you're not using an STA, then there are differences you have to pay attention to (camband slot spacing, mainly). There may be some other issues, but that's the problem with buying piecemeal.
I added up the prices of what you've listed, and once you add the STA and cambands, you're looking at spending about $470. For less than that, you might consider going with a full package that was made to work together as a complete system - check out the Deep Sea Supply package configured as such:
Single Tank Rig w/ Medium Stainless Steel plate, Hogarthian Harness, Torus 26, Full Circle Style Single Tank Wing

DSS rigs are fantastic, and do not require an STA. Plus, the owner, Tobin, is readily available here to answer any questions you may have and make sure you're outfitted with the best (not most expensive) equipment for the type of diving that you do. I'm not in any way affiliated with them, but I do like their products.
Best of luck!
