The apricot and peach are the only ones I would consider for indoor living, the rest of the trees should be outside. Do you know what rootstock they are on? As you already have a fan trained tree on the wall you will need to chose which form to use on any trees you add.
The kiwis could be trained up the glass sides but they are very vigorous and will need regular attention to keep them in bounds.
Have you considered melons? They would do well in such a fabulous glasshouse.
Yes cutting the leader stem out of your plums and cherries is essential, often already done when you buy them, unless they are just 1st year maiden plants. I would do that this summer. Unless they are on pixie stock they will still want to get too large, I think, for that space and don’t need or want to be inside. Have you no suitable space outside, is that why you need to grow them indoors? Also I wonder why your plum guy sold you two of the same variety? Check if Mallard is self-fertile, otherwise you will need another compatible tree for a pollinating partner. Even self-fertile trees fruit better with a partner.
OK I looked it up for you, sorry, it’s not. Mallard is self-incompatible according to both thr RHS and the Malling research institute (world expert on fruit production) and needs a different pollinating partner to set fruit. See the chart on p5/6:
Forgive me, Tagwex but you asked for advice on pollination, suitable soils, which trees were suited to being kept in your orangery but you seem a little reluctant to take on board what we are all saying. Of course it’s your orangery your choice and if you want to restrict hardy outdoor trees to pots indoors that’s your choice and I wish you well with your project. I think most of us would kill for a structure like and all the growing possibilities it offers, so are just a bit baffled as to why you would want to!!
Mountainous Northern Catalunya, Spain. Hot summers, cold winters.
Apricots, peaches, almonds and olives is what I would have in there, along with the grape you have and possibly a fig though they also want to get big.
Would cherries and plums even like the warm temperatures inside there? and how are you going to pollinate everything?
I think the sunny south east of Ireland is possibly wetter and maybe slightly colder than central Norfolk so to guarantee a fig crop, maybe the plant should be in the orangery.
I doubt if it’s colder than here ... winter winds straight from Siberia via the North Sea 🧊 💨 but it is probably wetter ... we have to water our fig at least once a day in summer 😊.
As I said, the OP should improve on our cropping if his fig is indoors. He should get at least two flushes of fruit ... possibly three. I’d grow figs indoors if I had the space ... but then I wouldn’t grow Brown Turkey ... there are much choicer varieties if you can provide the right conditions. 😊
Where we are is the warmest sunniest and driest part of the emerald isle statistically. The west coast gets all the rain with Galway being similar to Manchester as being the wettest area. I only got brown turkey as it was all that was left at the very end of the bare root season.

I'm putting a wigwam around the kiwis. Melon seeds just cannot be got around here this year, see another thread. I did manage to get a packet of water melons though as a last resort I wanted honey dew. The nursery where purchased and a horticulturist friend has advised that all will be ok in the orangery.
Your plums and cherries really need to go outside, I don’t think you are going to have the space (each 4x4m approx) and don’t think they need to be undercover, they are pretty hardy. All of the berries and currants in list 2 need to go outside, the blueberries in acidic soil. Save your orangery for those that need extra protection. You can look up online each tree variety regarding whether they are self-fertile or if they need a pollinating partner.
Part of the reasoning for planting inside is to keep the birds away.

Checked that out... mallard is self sterile. Stupid question incoming.... having two self sterile plums will they pollinate each other?

Thanks for that info... I am taking on board ALL advice given. Fruit trees are new to me. Yes indeed mallard is self sterile, looks like I will have to ask around the neighbours to see if anyone has another variety of plum and rob their pollen or else go back to the garden centre. I am getting conflicting advice which is adding to the problem. I don't know why you would say I am being reluctant as not one tree is planted yet. They are still in their pots outside the orangery.
