A 'discard' is a type of send, and the card is sent from your hand.
Yes, both will trigger, and the opponent will discard a card for each.
The answer is NO. If there is a cost requiring you to discard a card, you cannot play it. You also can't, for example, play a Card Destruction if there are no cards in either players hand or play Raigeki when your opponent controls no monsters.
You cannot voluntarily just send a card from hand or field to the graveyard for no reason. It can only do so if its text specifically lets you, or you do it for the cost, or by the effect of another card.
There is no phase 10 and there is no wild card.
Just take a card from your hand and place it in the Graveyard pile. You can only do it when directed to by an effect, or you have more than six cards in hand at the end of your end phase. You can never discard a card for no reason.
Raigeki Break is a Normal Trap Card. "Discard one card to destroy one card on the field."
You can't ever just discard cards for no reason, you can only do so if instructed to by a card effect or a game rule, such as the one that lets you replace one Field Spell Card with another.
It's called a "Discard all" card. - When played, you must discard all cards of the color of the discard all card (E.g: If the top card on the discard pile is a blue 4, the player may play a blue discard all card and discard all their blue cards.)
The X card means discard all. When played, you discard all cards of the same color as the discard all card(e.g; if the card on the top of the pile is a green 6, you may play a green discard all card and discard all your green cards.) Play resumes after the player who played the discard all card.
You cannot simply choose to discard a card from hand, voluntarily, or send cards from the field. You can only do so when allowed to do so for a cost, or instructed to by an effect or game mechanic.

Ye,s If it matches that card on the discard pile. Otherwise, you pass your turn.

No, you cannot discard a card at random, unless you have more than 6 cards in your hand at the end of your turn; then you have to discard 1 card.
If you have a treasure card(s) in your deck, you will need to discard one card in your deck to draw a treasure card. Right click on a card to discard, then if you have a treasure card(s) in your deck, the "Draw" button at the bottom will be clickable, and this will draw one random treasure card into your hand when you click on them. You will need to discard one card to draw one treasure card, so if you need two treasure cards, discard two cards in your hand and click the Draw button two times.
