No because you must send ALL of the fusion material from the main deck to the graveyard.
Since one of Dragon Knight's material is any Dragon type Synchro monster you can't send it from the main deck since it would exist in the extra deck.

You need to Fusion Summon it by using 'Black Luster Soldier' and 'Blue-Eyes Ultimate Dragon'. You must use Fusion Summon, so cannot being it out using cards like 'Cyber Stein' or 'Summoner of Illusions'. However you can use Fusion Substitutes like 'King of the Swamp' in place of one of the components.
Yes, there are many Fusion monsters that do not need specific Fusion Material monsters. Basically, if a Fusion monster does not say "This monster can only be Fusion Summoned with the the listed Fusion Material monsters", it can be Fusion Summoned using one Substitute Fusion Material monster and the other required monsters.For example, "Blue-Eyes Ultimate Dragon" does not state you must use the three "Blue-Eyes White Dragon"s listed, so you can use one Substitute Fusion Material monster. "Chimeratech Overdragon" is special because it states you must fuse it using one "Cyber Dragon" and any number of Machine-type monsters. You can use a Substitute Fusion Material monster in place of "Cyber Dragon", but you cannot replace any of the Machine-type monsters with one.
It can indeed. Both have 5000 base ATK. Five-Headed Dragon cannot be destroyed by battle unless by a LIGHT monster, which Dragon Master Knight is. Normally both would be destroyed due to having the same ATK, but if there is another dragon on your side of the field, your Dragon Master Knight will be 5500 ATK and survive battle with Five-Headed Dragon.

Dark Paladin and Dark Flare Knight both list Dark Magician as a Fusion Material monster.
