I know a few crosses, one crossed with TB and another with warmblood. They are both fairly decent horses, considering I've seen a LOT of conformational disasters with crosses like that:P And they both can jump in the 3'-3'6" range, with presentable jumping style. They are definitely not totally horrifying, nor are they any sort of outstanding example of a jumper, but they get around fine. It really depends on the individual horse though, what they'd be suitable for. Some will be able to jump, and some won't.
Friesians are totally different types of horses compared to the horses you listed. Which is why there are so many franken-horse crosses out there. When you breed similar types, you are more likely to get something that resembles the dam and sire. When you breed 2 totally different types, there is a tiny chance you might get something half decently put together, but more than likely you're going to get a total mish mash of parts that don't really go together, for example a friesian high stepping front end with an arab's hind end, and then the height would be a crapshoot, you might end up with a hony. Or get that big friesian body on spindly TB legs. I've seen that too, it's not pretty:P
Not sure if you are just wondering in general or because you are looking for yourself, but I wouldn't recommend breeding a cross like that, there's just too many variables and it is a total crapshoot. You'd be better off doing a lot of horse shopping for that one great looking cross already on the market that is built for what you want to do.
