Buying more orchids

[Sonicles]

I feel a little cheeky as I have already had so much information from the members here & have only been a member for 5 mins but I have also read the very interesting advice offered via stickies. The thing is I have been looking to see what is available in my area (UK) to buy & I have found what seems like a good supplier. I have chosen 3 plants which seem to be suitable to grow in my conditions, but it seemed silly to go ahead with my purchase without asking for opinions here.
The 3 I have selected are:-
Burrageara Nelly Isler Orange
Encyclia brassavolae
Laelia (Sophronitis) hypophylla

I welcome any advice you feel able to offer as to whether these will be suitable at my stage of the learning journey. I attached photos as supplied by the supplier.
