It sounds like the jumper cable connection wasn't letting enough amperage through to do the job, or the connections between the battery and starter motor on your bro's car are corroded, etc. Either way, as long as the starter is good, the missing link is power getting to it.

Im sure the alternator is fine just like mother said it sounds like the jumper cables or a could be bad contacts on your bros battery. I would replace his battery and see if that helps. If it does not than i way wrong at it could be the alternator. Hope i helped. God Bless-Mitch

As long as the jumper cables were left on, the other car should have kept running. Even if you removed the alternator & the battery from the other car, the jumper cables should be more then enough to keep it running. If it dies as soon as the cables are removed, then the likely faults would be either the battery or the alternator, but you can't tell which one without the Blazer running on it's own. So, swap the batteries & get it running, then you can test the alternator.

They connected the jump leads wrongly? If the leads are connected right the alternator is irrelevant.

if its a new battery then make sure that the cables are not able to move in any way. Have your Bro. grab the wires (one at a time) that connects to the battery close to the terminal and move it back and forth if they move tighten them, put a charger on it try to start it in a little bit (30 or so min. should work, if no charger, leave the jumper cables on for 5 or so min.) then go straight to the auto parts store and but some terminal protective spray.
