English is kind of weak in this arena because we only have one word for love, but we can modify it to be more useful: romantic love and fraternal love. Any other use stems from these two, and will basically boil down to "I like ___a lot."
Another specification is when people ask "Do you love them, or are you in love with them?"
"In love" means romantic love, I think. You want to spend your life with this person, probably every day, will overlook their faults and are enamored with the things they do, the way their brain works, etc.
