Welcome to Librarium Online!
I have five horssemen (one unit) now do you guys find that if you have say three small units of six or five tend to run into eachother or cant get the flank charges since one of the three units already has. And wouldn't two large units have difficulty manovering since there size is much larger.
Anyhelp regarding my favorite unit would be great. Keep in mind that my army is a marauder army and I will have at most one unit of warriors.

I use one unit of five on occasion and their main job is to annoy enemy ranked units (by march blocking them and flinging the odd axe their way). They also intercept enemy skirmishers and other light cavalry when needed. Since I only use one unit, they never seem to get in the way or get stuck themselves (being fast cav there's never a reason why they should get stuck between terrain pieces). Though if you had several units of them, they may get in each others way, but if you kept just one unit on each flank, there should be too much of a problem.
Against High Elves, they should be quite useful to block the enemy fast cavalry but obviously watch out for shooters and wizards who will make short work of a small unit of lightly armoured horsemen. Against high elf basic infantry, I would also use them as flank attackers.
When it comes to undead, the horsemen aren't quite as reliable, since they'll have to be passing fear tests all the time, and being away from the general doesn't help with this. Once again though, there are several units in Vampire armies that need intercepting, like Fell Bats, Dire Wolves and Ghouls. There is one thing that horsemen can be rather good at, and that's finding and assassinating Necromancers.
As for armament, many players give their horsemen with flails (OMGZ!! +2 strength!), but if you fail to drive off the enemy by the end of the first round, your men are lumbered with two handed weapons that have no benefits. I much prefer spears, shields and throwing axes. The spear and shield combo means I get +1 strength on the charge and a reasonable save of 5+. The throwing axes are just used as opportunities present themselves, but rarely do they do anything spectacular (though I did kill an Ogre Irongut with them once).

there is no reason to use more than 2 units of 5. That is my opinion. You could use a unit of 10 and have fun shooting. oh well i dont know what im talking about, i hate shooting.
