Do I have the correct 110 mm soil sockets to connect these bends to a soil pipe?

These are (from right):

a) pushfit WC bent pan connector
b) pushfit bend with one plain end and one socket
c) soil pipe with plain end first then socket

d) solvent weld bend with plain end first, then socket (probably a good idea if this is solvent weld as going through a brick wall and will be in accessible once complete as will have a bath located over it)

e) plain end soil pipe

For example, the soil pipe (c) doesn't have to be around the other direction with two plain ends on the bend (b)? Or bend (b) doesn't have to have two sockets?

Or perhaps the solvent weld bend (d) should have a socket on each end with a plain end soil pipe as (c) going into it?

When you say you have a soil pipe to connect into is it plastic or cast.

Plastic.

(E) is the plastic soil pipe already in place which goes directly through a brick wall and is already connected to the stack.

The above image is essentially a plan diagram.

Bend d is a 90 degree knuckle bend, myself i would not use one. Should be a slower bend like b.

If possible get a solvent weld to push adapter for d
Turn c and b around so no waste collects at the push joint

Like this (below)? That would mean the pan connector (A2) going directly into a pushfit socket (B2). Is that correct?

Scott_d, do you mean a solvent weld adapter between C2 & D2?

I'm unfamiliar with the adapters you refer to. Would it perhaps be one of those shown in this link?

I suppose it would be okay too (if I can get one) to get a bend as per B2 but with a plain end on each end?

I have had a look to determine if such a product exists. I can't seem to locate one, so this may not be an option.

I should have clarified it was a 110mm bend (B2) but with a plain end on each end of it which I couldn't locate.

Your first picture the pipes are the wrong way round for the direction of flow. Sorry you can not get a double plain end bend they do not exist. Your last picture is the right way round to the flow and all you need is to cut a small 2 inch piece of plain 110 pipe to fit into the socket of B2 for the pan connector to fit into.
 
The sockets are supposed to run the other way. Flow into a socket not facing down. Bad practice as it puts pressure on the joints and will be more prone to leakage.
