First of all, the red juices aren't blood. Luckily, Ribeye is one of the few steak cuts that is edible when cooked beyond medium.
There are many different ways to cook a steak, but for a beginner I would focus more on learning how to cook a steak in a frying pan. Get it very hot (smoking), season and lightly oil the steak, before placing it in the pan. Cook for 30 seconds and flip, then turn the heat down to medium, and continue flipping every 30 seconds until it's done to your taste. For an 8 oz, I'd reckon about a total cooking time of 6 minutes would be fine for medium, which will still be a little pink but without the 'red juices'. Leave to rest somewhere warm for a couple of minutes before serving.
The timing is really all about feeling and experience though, so it's a skill that's very difficult to impart through the internet. Best to practice. Also, if you're cooking all four steaks at the same time, make sure you use a big enough pan, or use two separate pans.
