What is the top dimension of the 25.4mm post.

The top part (the narrower part) for holding the clamp, it's diameter is about 22.15mm.

Help! 25.4mm is too thin that it falls into the frame and I can’t tighten around the seat post any tighter. What should I do?

If you're set on keeping this post, you could always purchase shims

My seat clamp says 25.4-28.6. What does that mean and will this post fit with seat clamp?

The post that i ordered was 27.2 so your clamp can fit into when you tighten it

If you are asking will a 30mm seakt post fit a 31.8 mm ophening in frame- no.
