yes, they perfectly will approach to your pant suit/skirt suits
Well, they are all rather staid and conservative. If that is what is required in your professional life, or it suits your personal style, then they are fine.
Sure, they are great, would go perfect with a skirt, and pants too.
To me those look like shoes my elderly aunt would wear...and she wears orthopedic looking shoes. Seems to me a woman in her 30s could wear something much more modern. I'm 48 and I'd never wear any of those, but I don't know about foot issues or personal preference or employment, so you'll do what you want anyway.
Not really with a suit. A dressier full leather slip on heel, pump, or flat. Casual wear..is more for straps and ties.
