It is a 6ft red robin which we moved to another spot in the garden but it hasn’t taken to its new place. We have given it loads of water and plant food as well but it’s seems to be shrivelling up.
It is likely being overfertilized and overwatered. Feeding should not occur until the roots have fully adjusted and healed. Watering should be kept to what is needed, only.
Feeding will not be necessary until it is established. You will know when that happens, as the new growth will come out very quickly.
Watering will need to be done, only, when the top 3 inches of soil are completely dry. This will prevent overwatering, which leads to root suffocation and infection.
I would treat with a fungicide. This article will help:

One plant had some type of bug eating the leaves and another plant looked like the leaves had issues with mold. I used a spray product that was probably not pure neem oil. I sprayed them in the afternoon of an 80-plus day! So I now know to use a 100% product diluted with soap and apply on a cool day! Now the leaves are wilted. (not dead but not good looking) If I pull the plants out and toss them, should I remove the soil they were planted in also?
Neem Oil comes in ready to use spray, concentrates, as well as other forms. It breaks down quickly in soil and water. If yours was a ready to use spray, it didn't need to be diluted. However, spraying during the hottest part of the day is a no-no. Always spray in early morning or evening. If the leaves are just wilted, but not brown or dead, I wouldn't pull them out just yet. They might survive. And if you do pull them out, wait about a month before replanting to be sure the chemical has broken down.

I have 3 red Robin and the middle one did not get any new leaves and is now bare. I know there is a common fungus but cant find any evidence of it. Most of the branches are still bendy. Can I revive it do you think?
This looks to have succumbed to Fire blight! You can attempt to treat with a fungicide, then prune out any dead or severely injured branches that do not have bend to them.

I have two ornamental red robin trees which have survived fine over winter. New shoots on both trees are red but crusty and dry. Old leaves seem to be unaffected. Any help would be appreciated

I have two red robins which I planted in March. They were fine at the beginning but now seem to be growing horizontally rather than vertically. Would you have any idea why this might be? Many thanks.
This can happen when they receive too much shade. Sometimes, pruning and feeding can help, though.

My Red Robins look like they are being eaten. I have found baby snails sitting amongst the leaves. Are the Snails doing this as some of the damage looks too much for a tiny Snail ( note I cannot see any larger Snails around the plants)
Even small snails can do big damage! This article will help you to get rid of them:
