All sorts, think of a household item and then some and you get the picture. I thought this was a phone when I first saw it
Can't do 4. Tried for many an hour. Just can't seem to get the timing right. Probably got to the same stage as you regarding 2 balls in each hand but not all at once. Clubs are easy. Took me a couple of hours to go from 3 balls to 3 clubs. Looks impressive even though it's basically the same. Just got to get a feel for the spin and give yourself a bit more room.
First of all, I am not a good juggler. Secondly, there is a rhythm to it. Practice until you get started with 3 balls. It is quite easy. Just a bit of patience required. I managed it within half an hour or so. It wasn't very elegant but it was juggling of sorts. Then over time it just becomes really easy so you start trying different tricks and different heights and different size and weight of things. Juggling 3 objects of differing weight and size is very hard. Harder than the clubs.
I'm sure you're a lovely fella but I'm not that way inclined. All the best finding someone though. Have an emoji to cheer yourself up....
I've got a vision of you seeing a dumped dead body of a woman and muttering " oh my god, who left this here, what a waste". Then going over and wrestling what you thought may have been a new iPhone 7 from her hands.
