No, of course not. Summoning Sickness stops a creature from attacking or using an ability with a Tap symbol as a cost. It does not stop it from being tapped by other effects, or for certain costs which require a tap, but do not use the Tap symbol (they can be used for Convoke for example) and they are certainly not destroyed if they end up tapped.
Yes. The chain will finish resolving first of all, summoning your Fusion Monster. Elemental Hero Absolute Zero's effect will then activate, destroying your Fusion Monster unless you have a way to save it.
In a sense, yes. You attack once per monster. But if one of those monsters was just summoned that same turn, then you cannot attack with it due to summoning sickness which lasts for one turn after summon.
Synchro Summoning is the process of Special Summoning a Synchro Monster from your Extra Deck onto your side of the field by utilizing a Tuner Monster and various non-Tuner Monsters whose combined Levels must match the Level of the Synchro Monster.

Monster cards do not have life points and there is no concept of 'damaging' a monster card except for battle. In battle a monster either dies or it does not, there is no accumulating damage such as in Magic the Gathering. A monster can fight off an infinite amount of monsters that are weaker than it, but is destroyed if it battles with one of equal or greater power.
Black dragons is the best!
No, if your attacking Monster is destroyed by an opponent's "Sakuretsu Armor" it is considered destroyed as the result of an effect.In order for a Monster to be considered destroyed as a result of battle, the attacking Monster must have been destroyed because its ATK was equal or less than the opponent's attack position Monster it battled with.
destroyed by battle or by card effects
As long as you are Special Summoning before, or during the Battle Phase, then yes, that monster can attack.
Your monster is destroyed if the monster you attack is in attack position, and you lose life points.
All Ritual Summons are considered a Special Summon. However, not all Special Summons are considered a Ritual Summon. A Ritual Summon can only be performed with a Ritual Spell Card and a Ritual Monster. A Special Summon refers to any monster that is placed on the field in a way that is not a Normal Summon, Flip Summon, or Set. Also, Ritual Summons are never considered a Normal Summon.
In the Yu-Gi-Oh card game, 'life points' is the number given to each player at the beginning of a duel. typically each player will start with 8000, and subtract or add to that amount from there after. If a monster attacks directly, its attack is subtracted directly from the opposing players life points; if a monster battles another, the one with higher attack will remain, and the player whose monster was destroyed will take the difference of attack points to their life points, unless one monster is in defense position, wherein no damage is inflicted unless the attacking monster's attack is less than the defending monster's defense. In this case, the attacking player would take the difference in the attacking monster's attack and the defending monster's defense. The stars you're referring to are the level of the monster. A monster with 3 stars is level 3; 5 is level 5; 8 is level 8. These are used in tribute summoning monsters, synchro summoning monsters, and XYZ summoning monsters, and other special circumstances.
Yes, of course. Nothing about tribute summoning itself stops you attacking, only if you used something like Soul Exchange that forces you to skip your battle phase.
