No, no developer can make a significant change to the Bitcoin Blockchain. Also, as everyone else said, it's open source. You can contribute to it, so the number you came with (5 Devs) is very stupid and irrelevant to this conversation. Here is a screenshot of the GitHub Repo of number of contributors. And it's surely above 5... (https://github.com/bitcoin/bitcoin)

There are 5 Bitcoin Core maintainers who hold the keys to implement changes: Hennadii Stepanov, Michael Ford, Andrew Chow, Marko Falke, and Gloria Zhao.

Each is responsible for an aspect of Bitcoin; for example, Stepanov maintains the network’s graphical user interface, while Ford oversees the build system.

Gloria Zhao, the only woman in the maintainers’ team, writes and reviews the code that governs Bitcoin’s transaction validation process.
Andrew Chow is in charge of programming for crypto wallets, which allow investors to store their bitcoin, while Marco Falke focuses on testing.

Together, these coders keep Bitcoin’s digital ledger up to date on its network’s thousands of computers. They must ensure that the software
remains compatible with the latest versions of operating systems like Windows or MacOS and that it keeps up with transaction volumes.
