Usage of direction and location (destination) complements (衣服都装进箱子里去了 vs. 衣服都装到箱子里了)
The first example:
“衣服都装进箱子里去了” and “衣服都装到箱子里去了”
has the same meaning and is both OK.
The only difference I think is the former one indicates the action(put in) but the latter one emphasises on the state of the clothes.I am not sure because these two are almost the same in daily use and nobody will notice the difference between them.

For the third example:
You can use a direction complement.
“气球升到天上去了” /“气球升上天了”
However native speakers do not use “气球升上天上去了”.
Because the meaning of “天上” contains both location(天) and direction(上).
