Tv input question

[Isaaccoker]

Can I plug like 5 or more inputs into one box and be able to just flip threw the channels list (my tv has only one input and it's coax)

Yes

You should be able to get a video switcher for RCA video that can output to COAX. Old VCRs also used to be able to produce an analog signal for a COAX input. I don't know if anyone would have made a HDMI video switcher with a COAX output.
Any PAL or NTSC television though is going to look terrible though compared to a modern LCD or Plasma television.
