Will these fit a guy comfortably?

prob Not they are WOMANS underwear

What's size 5 equivalent to? Small? Medium??

I wear Size 6 clothing. I am usually considered to be "Size Small" in most women's clothing, also. In the case of these particular panties, which are a made of a very soft, lightweight, knit, that is very stretchy, and form-fitting, and feels like a second skin, I ordered Size SMALL, even though the website gave me a guidance message for this item, that said, "Based on purchases by customers who wear your size, Medium will fit you best". I always read through several customer Reviews when buying clothing online, to see how they say that the item fits them: loose, tight, true-to-size, etc. What I ultimately used, to decide, which size to buy, for these panties, specifically, was the provided "Size Chart" [Eiggam Size Chart] for this item, which uses the actual waist and hip measurements to determine the size to buy. I used my tape measure: I have a 27" waist and 36" hips. Despite, the guidance message, to me, saying that "Medium will fit you best", the Size Chart said this: S(mall) (Waist) 26 - 27 (Hips) 36 - 37.5. So, I ordered the small. They fit me perfectly, and are quite comfortable. I hope this information helps!

As the size is to big for me, they fit me more as a high waist

Can't remember the color choices, but I'm thinking they are a variety, or I would have ordered in just 1 or 2 colors. Sorry I don't have a direct yes or no answer for you.
