Hope it helped!

The main takeaway is that more funds doesn't necessarily mean you're more diversified. I have VTIAX and VFWAX, but they're pretty much the same thing. Likewise with VOO and VTI.

The important thing is to decide what allocation you want, and then buy funds that provide that. Unfortunately, there are as many fund allocation strategies as funds, so it can be complicated.

Good luck! I'm happy to answer any questions.
