The Jag looks like it will shine up like new. Coppertone was a great color. It looks entirely original except for the grips. I would take it completely apart and clean, polish each part. The first thing would be to take out the batteries if there are any in the tank.
The musclebike is a Huffy with a bent fork. The banana seat isn't torn up, so I'd say it's a rider. The serial number will give you the year. The first digit is the year followed by an H, an 8 would be 1968 (or 58, etc) but that bike is most probably from the 60's.
