OK - now we are getting somewhere!

To start, in the first two images you shutter speed is WAY too slow to handhold and the consequence is a blurred photo. To handhold a 50mm, you really want to be at a 1/60 or faster. Better yet, 1/125.
The lighting on all three is pretty good - it has direction and is not too low.

The vignette on #1 is a bit heavy-handed, IMO, but that is your call.

Number two is awfully close. In particular with a 50mm, you really do not want to get that close - a bit farther back would be more flattering. To that point, #3 is perfect for a 50mm.

Number two is too soft - not soft in a good way - soft as in blurry. A 1/15 shutter and an aperture that wide open gives you an unacceptable image. Nothing is sharp. To be honest, this is a throw away. Yeah, I know, others will tell you she's beautiful and you should keep it. I will go along with the beautiful - but the photo - not so good.

Now to the skin: Photoshop and elements have a healing brush that is perfect for smoothing out individual blemishes. You can also use the clone stamp by setting the Mode to Lighten, opacity to around 33%, and sampling from clean skin. I use that ALL the time and it is fantastic for cleaning up areas.
There are many ways to smooth skin some are better on some skin than others - you need to use the one that works on your image.
There are a bunch of third-party offerings that do a great job on skin, but I have no idea how the Paintshop thing works, but I suppose there are plug-ins for that - I'm a 100% Photoshop guy and ignorant of the other stuff.

So - get that shutter speed up over 1/60 and for MOST portrait work, shooting at f4 or less makes no sense - the DOF is just too shallow. For some special images, sure, but you will have a lot of marginal to unacceptable images.
