The palm looks like Trachycarpus to me - perfectly hardy. I have one roughly the same size in a pot that's about 30cm in diameter.
I would plant the palm and the pine in separate containers though.
I would recommend going for John Innes no. 3 if you're unsure. It's what you would use for most shrubs and trees that are going to be in their pots for a long time.
There isn't 'one correct answer' to your query - that's the problem. I'm suggesting JI no.3 as it's a simple solution. In reality I tend to improvise my potting compost for cost and convenience, for example mixing cheap multipurpose compost with soil and sand to make soil that is similar-ish to JI no.3. But that's a bit complicated to get across so I would say stick with JI no.3 as it's fit-for-purpose straight out of the bag.
The confusion about peat came from @Fairygirl 's first post...don't understand why you have to be passive aggressive. It's very easy to ignore this thread and be done with it...
The only reason I said not peat free compost is because its mostly rubbish. I apologise if that meant someone misunderstood, but I did clarify later on that pines only needed some basic soil to grow in, which they do, and that they only need to be in a soil that's 'not alkaline' - as that isn't suitable for them to do well.
I do feel that many people have bent over backwards to try and help the OP, but I'm not sure any of it is being taken in
It's a place where beautiful isn't enough of a word....
