That shouldn't be too hard to figure out but first let's make sure we're talking the same language and same bits. The bearing races are in the head tube. Okay. The first item that goes on the fork is called the crown race (because it sits against the fork crown). It is usually press-fit on and normally can't be removed easily without the proper persuasion tools. Let's assume you left that in place. I see bearings stuck on the crown race. Are they caged? I'd guess not from the pics. Let's assume grease is holding them there. If so then you should be able to insert the steerer tube into the head tube until the bearings seat against the lower head tube race. Once you get them there, keep the weight of the frame on them so the fork and frame don't separate. Otherwise the bearings could scatter.

BTW, the normal procedure is you turn the frame over, fill the lower head tube race with grease, insert the bearings, then put the fork in from above. You hold them together while you turn the frame back over to work on the top, keeping the fork and frame pressed together.

After all that, it looks like you have too many pieces. The normal procedure is next you put grease into the upper head tube race, put all the bearings in, screw down the cone onto the steerer, put the keyed lockwasher on the steerer tube, then screw down the final locking nut. Your headset may have races which still have to inserted into the parts in the head tube. Or else you picked up some from another bike. Or that headset is different from any I've seen.
