You can usually tell by driving in tight circles on gravel. You can also tell by jacking up the tractor. Keep in mind it will not actually be '4' wheel drive. It will be one front wheel and one rear wheel unless the diff-lock is engaged then it will be 2 rear and one front.

I would use your front loader to lift the front wheels, then back up. As Aaron said, only one of the front wheels will turn if engaged.
Sometimes my lever doesn't move. I just move the shiifter in and out of gear with the brakes locked, then move the lever. You should travel close to a foot if working.
my front wheel drive worked fine last year. now it does not work at all. I can make the lever go down but the front wheels don't turn. I took the clamshell covers off so I can turn the drive shaft by hand when it is parked and in gear with engine off and 4 wheel drive selected with lever all the way down. Shouldn't I not be able to turn the drive shaft when it is in gear and the front wheel drive selected?
You are correct. I believe your drive shaft is splined onto both the drop box shaft and the front wheel drive pinion. If the shaft coming out of the transmission is turning with 4 wheel drive engaged then something Is wrong in the transmission. could be shifter, could be gears.
I can't give you a good answer. I am pretty sure you should be able to feel when a detent ball goes in a groove. Also, if moving very slowly and try engaging the lever. You should feel at least a grind or some indication something is trying to engage. The parts drawings here don't seem to show the transmission front wheel drive gears or maybe I just don't recognize them. Does this look like your shifter? I can only guess 3 forwards, 2 ranges on right lever and the other lever maybe the pto?? https://www.hoyetractor.com/CTGY/1401SHIFT.htm

I thought the 4 wheel selector lever was supposed to be down for 4 wheel drive. It is selected in the upward position. I was tired after fighting with the driveshaft to put it on the tractor so I got things mixed up. Works fine now.

Well now, that was an easy fix, happy tractoring.
