How Should I Proceed in the 'Job Interview Aftermath'?

I’m moving to Denver, CO from Texas, and have therefore been looking for a new job in Denver hopefully that I can start when I get up there at the end of August. So my job search has been conducted entirely remotely (email, phone, etc).

So I had two big interviews earlier this week, one on Monday, one on Tuesday. I sent “thank-you” emails as a follow-up on Thursday, and it’s now Friday and I haven’t gotten a decision from either of the places. For both interviews, the job would be a full-time permanent web marketing position, at a relatively median level of pay. So it’s not like I’m waiting to hear if I got a part-time gig at the coffee shop.

Now that the week is ending, and still have no word, I’m trying to figure out the best course of action, and have these questions running through my mind:

How long does it usually take for this type of response to come back from potential employers? What do I do next? When should I follow up again? What should I say when I do follow up? Should I expect an answer from them even if they decide not to hire me? How long should I wait for an answer? Should I still be heavily invested in my work search elsewhere?

That’s the meat and taters of it.
