The blue open wheel car may be a Maserati, or a Lancia F1 car. The light color car with blue stripe is probably an early McLaren or Lola T70 body. The chassis looks state of the art for it's era, and I believe the telltale gold can may indicate a Russkit motor.
Be careful with those two vacuumed formed bodies, they're old, and NOT Lexan. The bodies back then were formed using Butyrate, a clear plastic material that usually yellows with age and also gets brittle. It was commonly used in commercial packaging and the hobby picked up on using the material and equipment already in place at the time. You've noticed the rippling on the edges of the bodies, I'm sure. This is also very common. Be gentle, they will not survive many bangs on a high speed commercial track, or even a home circuit for that matter. There are modern Lexan reproduction bodies of various styles available, you may want to paint and mount up a couple of those if you plan to run the cars a bit, saving the originals for posterity.
Of course, lightly oil and apply low voltage to the cars at first before letting them rip at full throttle. The guide flag, braid, tires, gears, axles, ect. obviously need to be inspected and adjusted or replaced as well. I know it's common knowledge but still good advice just the same, better to have the car run smoothly first time out instead of launching off onto the floor or burning out a nice original motor.
Hope this helps you to have lots of FUN from those four vintage rides. Enjoy! -- Ernie :>)
