at not be the right place to have focused but Thought if I focused half way I would be more likely to have a in focus shot
You need to understand what "in focus" means. It is not the same as "sharp", although something that is in focus through a good lens will also be sharp.
A lens can be truly in focus at only one distance. The reason you need to focus the lens at all is so that you can choose what you want in focus and focus there. Everything nearer or further is out of focus - and therefore blurred - to some extent.
Fortunately our eyes can accommodate a certain amount of blur and still see the image sharply even though it is, in fact, slightly blurred. The range of distances where things look sharp enough is called the depth of field (DOF); it depends (among other things) on the f-stop you use.
There are plenty of complications to DOF but for general shots like yours a guideline is to focus about 1/3 of the way into the scene - but the half you chose is near enough most of the time. But what really controls how much of the picture looks sharp is the f-stop you use, not where you put the AF point. As it happens the f-numbers you used are more or less OK- you could have gone one stop smaller but that's not a big deal.
In the third everything is blurred. I think this gives a clue to at least part of your problem: you aren't giving the auto-focus system time to do its job. This is because of what you said above - you are shooting too quickly. Whenever you use autofocus you must give the camera to do that.
Another possible problem is that you are letting the camera choose which AF point)s) to use. If there are many things in the frame that could be chosen, most cameras choose the nearest or, at least, something pretty near. This might be what happened in your second shot - the grass isn't the nearest thing but it is pretty near.
no I didn’t have auto focus on. had single point focus on and can move it about, so each photo I set the focus where I wanted it ie 1st photo on the blue t shirt
Which is where the picture is sharpest, so in that shot it worked.
and the grass by the gardener on the 2nd one.
But (as I said above) not in this one ...
On the 3rd I think it was on his nose
… and here there is nothing in focus. Which in the absence of any other explanation is why I think you weren't giving the AF enough time to work.
So set your camera to use a single AF point and make sure you put that pint of the thing in the frame that you most want in focus.
However most of the pictures I cant put my finger on what I did wrong other than saying the photos just look

some of them look hazy and lacking in detail. Faces seem to lack contrast and when I crop 100% they don't seem sharp. In order to improve im trying to work out what did I do wrong. Can someone guide me in the right direction?
I know the photos aren't composed properly etc but at the moment im trying to improve my technique and understanding of light, camera settings etc.
From the below selection can you tell me if my settings were wrong,
In two of them you used -0.67EC. That has inevitably made them look dark, and that is exaggerated because you were shooting into the sun. As someone has already pointed out, those dark shadows can be lifted in post processing; but making everything dark to start with doesn't help.
thank you that makes sense
if its the capability of the camera/lens I'm using,
They are fine. The kit lens isn't super brilliant but that's not the source of your problem.
at least I know what to work on now and can’t blame the camera
is it the settings I used for the conditions ie harsh light
Your settings are a bit random. This may be because you used auto-exposure. Learn how to use the various exposure modes (aperture priority would be most suitable for these pictures) and keep ISO as low as possible.
i was using aperture priority so had set it in the belief that the f stop I chose would let in enough light to not need a high iso or a long shutter speed and increase my chances of a good quality photo. the iso is on auto though
The EXIF on at least one of them says Auto exposure, not Aperture priority. But in the situation you were there was plenty of light whatever the aperture you used. Choose aperture for DOF; set ISO manually as low as possible and see what shutter speed you camera chooses. Unless it's too slow to suppress blur (which in the light you had there won't happen) just take whatever shutter speed comes along.
As I say, your apertures (f-numbers) are OK - apparently more by luck than judgement - but your ISOs are too high and shutter speeds unnecessarily fast.
