I need emergency keys with a round tip on the bottom. are these keys round or square on the bottom.

These keys are a round very thick wire that's cut straight across at the end. They work very well for me; I have a Schlage lock.

can you open the doors with that has small button locks on the side.

I dont understand your question. However, these keys work on interior door with the push button lock only. Not the turn lock, that requires a different key

Are these keys compatible with schlage f40vsie619 door knobs?

Don't honestly know about that type of door knob but I can tell you that it didn't fit my door knob. They sent extremely thick keys and I have zero use for them.

Will this work on the yale lock for nest, for the battery replacement?

I do not know the type of lock you are referring but I do not think so. It is mainly for a small tiny “pinhole” like opening to pop lock on the other side.
