As with all things, I’d say context matters.
In general, I enjoy receiving compliments, including on my appearance, so long as they’re delivered in a respectful, no-pressure, and non-awkward way. I have received compliments from friends, coworkers, and even outright strangers on the street, in ways that were fine.
At the same time, you have to watch your context. I have received ‘compliments’ that were not fine, also, in my life (mainly to do with the pushy and presumptive way they were delivered). You have to be quite an obtuse jerk to make someone uncomfortable with a compliment, though, and I don’t think most men are in this camp. Some really are, though.
Sample details to consider: What is your relationship to each woman? What environment are you both in? What is her current mood (and are you paying attention to the feedback you’re already getting from her)? Will your compliments give her the wrong idea that you’re interested in a romantic relationship with her (potentially leading her on, if you deliver such compliments frequently and you can tell that she’s actually interested in you)? Does she seem to want commentary on her appearance, or seem to prefer commentary on other skillsets she displays?
Generally, be sensitive to the way each woman responds to your words and actions, and adapt on a case-by-case basis. Respect boundaries unconditionally if someone establishes them.
Not a lot to go on from your OP, so I’m keeping it fairly vague and catch-all myself. Is there a specific woman whose appearance you want to compliment in a specific way, in a specific setting, and that’s why you’re asking? Maybe run it past us for feedback, if so. Otherwise, use your best judgement, err on the side of respect, and be sensitive to however the person responds.
