Hi. Yes, 48x16 is a little undergeared - the hire bikes are 48x15 and 49x15 or similar is a pretty common training gear. That said, Fred Wright and Ethan Hayter were winning track league on restricted youth gearing until pretty recently so it's not all about the inches.
For the "pairs on the blue" drill, the solo rider should be on the lower "blue" line. So if you're the next rider to join, you just drop down above them. The next rider drops down to the blue line behind you, the next joins above them etc. If people don't stick to this, it causes gaps, confusion and potential risk.
