If aliens exist, some alien races could possibly have four tentacles on each arm instead of hands.

Probably. As nobody has discovered an alien life form (yet), we can't be certain that they would even have hands. However, the possibilities are so vast that there probably would be a few with eight fingers on each hand.
If there are real aliens somewhere in the world, they could possible have seven fingers on each hand.
