Whereabouts are you?
I ask becaus it might be more useful for us to recommend a decent bike shop that can listen to all that you've just told us and then see what they come up with?
In the short term though, get the 'dead' bikes up and running with a bit of TLC and some oil on the chain and see how riding out grabs you.
If you've been off a bike for a few years, like I was, you might find your tastes with regard to bike styling and comfort have changed!
