Not without using mods.
To get mod packs you must go to the forums for minecraft. There should be a forum that is for mods and you can find all the mods there. The first mod that you will need for minecraft would be the ModLoader, which is used to load all the mods that you will acquire.
You can't. But with resource packs or mods you can.

Yes, you play as the Arbiter in certain halo 2 campaign levels. I believe there are mods too. You can also select Elita as a character model in halo 2 multiplayer.
These mods are known for the quality (good textures/appearances) and quantity (lots of new stuff).

In halo 3 you can wield it i multiplayer and campaign. I have no idea about halo odst but it was not in the list of weapons not in odst so I imagine it is in there.
depends on what you're looking for. but most good mods in halo require a jtag. but a good site to look up mods is- http://www.thetechgame.com/
