There's no hard limit. Each of your monsters can attack once unless they've got effects that let them declare more, however as long as you can keep replacing your monsters with new ones without ending the battle phase, these can all declare attacks too.
for one monster, it can only attack once per turn, unless it says so on the card otherwise or by the effect of another card that lets a monster attack twice.
Each of your face-up monsters in Attack Position can only attack once during your turn's Battle Phase, unless otherwise specifically stated on the lore of a card..
You can have one Normal Summon or Set, and can perform as many Flip Summons and Special Summons as you have available resources to do so.
Only if it has an effect that lets it attack more than once per turn, like Asura Priest does.
Not inherently, no, they get one single attack like most monsters. They can only attack twice if an effect is letting them do so.
It lasts every end phase.
Your opponent will be able to destroy one of your Crystal Beast Amber Mammoths in battle even if two or more are on the field. If you redirect a attack to an Amber Mammoth, the conditions to activate another Amber Mammoth's effect would be gone because your opponent finished declaring an attack against a Crystal Beast Monster you control.
The red one!
Only if it has an effect that lets it attack more than once per turn, like Asura Priest does.
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.
yes but the damage from the first attack doesnt add on to the second attack
Not inherently, no, they get one single attack like most monsters. They can only attack twice if an effect is letting them do so.
A pawn can only move forward one square per turn(twice when it is being moved for the first time), but they attack dioganally(only one space diagonally though).
well there are a few but mostly its monsters effects that let you attack twice for example:elemental hero wildege and ultimate tyrano"Double Attack" is one spell card that does it.
It lasts every end phase.
Yes, it can.
You can attack with a monster and then tribute it in the same turn, yes. Obviously if you tribute it first, then it can't attack unless you've got a way to bring it back to the field.
No, it's not true. You get only one 'Normal Summon' per turn, but not only can other cards 'Special Summon' one or more monsters in the same turn as you do this, but other cards can let you Normal Summon more than once too.
Playing sports can put a physical strain on one's lungs, which, in turn, can lead to an asthma attack.
Yes. If you activate the effects of two Blackwing - Sirocco the Dawns, you can target the same monster twice.
