The official AC-adapter is rated at 1.25 A, so 1 A might not be enough in all situations. For example If you are using lots of peripherals or flashcarts or so. Chances are that 1 A is enough though.

I mean how much power it needs varies depending your situation. If you run into unexpected behaviour it may be due to insufficient power.

My Famicom is ok with 1 A with the Everdrive and external controllers and stuff, so I do think it is enough.
The disk drive part also draws power when reading or writing disks though.

Here's the datasheet for the 7805 voltage regulator.

https://www.sparkfun.com/datasheets/Components/LM7805.pdf

It's rated to a minimum input voltage of 7V and a maximum of 25V.

No worries running at 9V, well within spec.

Twin Famicom does not have a 7805.
