Any equivalents for these elements used in BOSS-NF1

[onelife]

I need equivalents for these transistors and diodes:
Diodes: 1S1588
Transistors:
   1. 2SC732TM-GR
   2. 2SK30A-Y
   3. 2SC1815-Y
If anyone knows for equivalents of these it would be great

These aren't perfect matches, but this is what I'd use:
1N4148 or 1N914
2N5088
2N5457
2N3904
