Q.Different Leaves Same Branch
I have a 2.5 year old potted lemon. It’s branches have 2 very different size and type of leaves on the same branch. Is this a problem?

Yes, the oddballs should be removed. If this is a grafted lemon tree, the strange branch is likely coming from the rootstalk, which is what the desirable upper part is grafted onto.
Cut it off at the base of the plant or where it is coming from. If all the branches are that way, the top part may have succumbed and the rootstalk took over.
You can cut off a branch and take it to the local extension office for confirmation that this is what is going on.
