If the sacrifice is a cost, then no. That'd be like paying one mana, and claiming it can be used for two different one mana abilities. Each cost needs its own payment.
Sometimes an effect triggers when something is sacrificed. In that case, one sacrifice will trigger all of them.
A creature with shroud cannot be targeted by instants, sorceries, or any other spells or abilities that target. However instants such as Evacuation will affect the creature because the spell does not target.
Abilities are not spells, but note that creatures and all other cards (but lands) are only spells in the moment they are cast and on the stack. So if you cast a creature spell, it's not a spell after it resolves.
You can combine the creature and it's abilities with another creature whenever you want until end of turn. So a 2/2 with banding and flying mixed with a 3/3 becomes a 5/5 flying.
While damage is still on the stack, the player who controls that creature has the opportunity to respond to the 'ping' by using the sacrifice outlet or any other instant or ability, if they choose to.
An Ooze token is a creature that can be created. The token card is the representation of that creature.
Vigilance just means the creature does not tap when it attacks. It can be tapped by other spell or abilities, or as the cost for an ability that requires tapping - and must of course be untapped for it to be able to even declare an attack.
Crown of Awe gives a creature (or creatures if you use its sacrifice ability) protection of red and black. That mean the creature can't be blocked by red and black creatures, be dealt damage from red and black sources, be targeted by abilities from red and black permanents, or be targeted by red and black spells.
No, unless they have haste.
I'm not sure I got the question right.but blue abilities in magic the gathering are usually:draw cards,counter spells andevasion abilities, for example: unblockable or flying
Creatures are not brought into play tapped, but they have summoning sickness preventing them from tapping to attack or to tap to activate any abilities unless they have the keyword "haste".
A permanent with shroud cannot be the target of spells or abilities.
Hexproof is a keyword ability. Something with hexproof cannot be the target of spells or abilities your opponents control. Note that if you control a creature with hexproof, and then an opponent gains control of it, you can't target it anymore.
