may someone help me build the startkde script?

In KDE 5, the software was split between 3 packaging groups:

KDE Frameworks: (or KF5) libraries which builds on Qt 5 but doesn't contain any end-user apps or anything. This is what is referenced by that "KDE: 5.52.0" version. Latest version is 5.60.0 (which I believe requires newer versions of Qt)
Plasma - the KDE desktop which builds on top of KF5 to provide the desktop experience. Current version is 5.16.4
KDE Applications - the various end-user applications, built on KF5. Current version is 19.04.3.

At the very least you'll need to also grab Plasma in order to get the working desktop. You'll also want to grab KDE Applications (which can be built individually as you please)
