Making vids

I am thinking about making more and better videos, I don't have a clue where to start. I have reached out to a couple of woman friends that I think might be willing to make some vids with me, not sure. I have 4 cameras so I can shoot different angles. I'm not sure which video software to use for mixing it all together and making the cuts. I have used MS ClipChamp some but not that much. Any helpful advice would be appreciated.
