No. A static QR code does not have a built-in expiration date. It directly encodes fixed information, such as a web address.
Adobe states that its static QR codes never expire. QR Code Generator likewise explains that its static codes remain active after a free trial ends because the data is embedded directly in the code.
Reading a code and reaching its destination are separate steps. An encoded address may become unavailable even though the code still contains it. Dynamic QR services add another dependency: their redirect links can be deactivated under the provider's service terms.
A static QR code does not expire by itself. Its destination or an intermediary service can still become unavailable.

No. Bluetooth can transmit audio directly between compatible devices without internet. Accessing the audio content is a separate requirement.

No. 5 GHz names a Wi-Fi frequency band; 5G names a generation of cellular technology. A home connection can use both, but they describe different links.
