You can use it yes, if a magsafe2 lines up correctly(?) which hardly seems likely

Might not be ideal but no harm

Find the right power adapter and cable for your Mac notebook ...

No. MagSafe 3 is essentially just a delivery system for USB power. It's a magnetic connector on one end and USB-C on the other. MagSafe 3 can be used with almost any USB-C output, including a 5V-only USB-C power supply or a USB-A power adapter with a USB-A to USB-C adapter.

I haven't heard of any adapters (like with MagSafe and MagSafe 2 which are compatible other than they physical shape of the connector), and I doubt they would be a good idea.
