Basic marine deep cycle battery questions

Would like ballpark estimates:

1. How long will a typical battery run an anchoring masthead light and a VHF radio without being recharged?

2. How long would it take a 4hp 4-stroke 2012 Evinrude outboard with alternator feature to recharge a typical battery enough provide at least an hour or so of VHF radio usage?

3. Is there a device that can tell you how much power (or "juice") is left in your battery - like a gas tank full/empty indicator?

Thanks once again for being such a great resource.
