The Extra Deck is just the new name for the Fusion Deck. It contains all your Fusion and Synchro Monsters.
A Side Deck is a group of 15 cards you can swap out in a Match Duel (a best two-out-of-three duel). How it works is after the first duel (or after the second duel if the score is tied), you can swap one or more cards out of your regular deck for the same number of cards from your Side Deck. This helps by adding cards on the spot to counter your opponent's deck.
During a Duel, your side deck is untouchable, nothing can affect it. Only in between the Duels in a Match, can side deck cards be switched with main deck cards, and therefore allow them to be used.
No. In order to make a legal deck, there must be a minimum of 40 cards in it; however, there is no max. You are also allowed to make a side deck with exactly 15 cards with which you can modify your current deck between duels. You can also have an "Extra Deck" which contains all your fusion and synchro monsters, but I believe you can only have 15 synchros or less. Hope that helps. ^-^
Since August 2008, a legal Yu-Gi-Oh deck has 40 to 60 cards in the main deck. It is no longer legal to have an 80 card deck (cards in your Extra or Side Decks do not count towards your main deck size limit).
In Match Duels (basically, you're playing best out of three with another duelist) a Side Deck can be used. A Side Deck is entirely separate from your main deck of cards and can only hold a max of 15 cards. After a duel is completed, before the next duel starts each player can look at the cards from their Side Deck and swap them with cards in their Main Deck. Cards included in the Side Deck would be ones to counter and adjust your strategy now that you have seen your opponent's deck in action. You might want to include extra Spell/ Trap removal against this one strategy or remove a card from your deck that doesn't function well against your opponent. In any case, cards taken out of the Side Deck must be replaced with cards from your Main Deck and vice-versa. Once players are done, the second duel begins. If there is a need to go into the third a final duel, each player can exchange cards in their Side Decks again if wanted.
If you're talking about main deck, then you can put any card in as long as it is a valid game-legal Yu-Gi-Oh! card (so no old God Cards)and is not forbidden by the current ban list, nor can you exceed the stated number of a restricted card. You also cannot put Synchro, Fusion or XYZ monsters in your main deck, these go in the Extra Deck, or Side Deck.
In Yu-Gi-Oh, a sideboard is called a side deck where you put extra cards in to switch out in between duels. However, a side deck must contain 15 cards or 0 cards.
You can only have between zero and 15 cards in your Side Deck.

No, but this is where the Side Deck comes into play. The side deck is composed of exactly 15 cards and is kept beside a player at all times. Between rounds in a tournament, a player can switch his/her side deck's cards out with his regular deck's cards as long as after the switch, he shows his next opponent that there are exactly 15 cards in his/her side deck.

The absolute MINIMUM amount of cards you can have in a Deck is 40 cards. Normally, for casual play, there is no "maximum" limit for the amount of cards you can have in your Deck. However, for most official Duels and tournaments, it is restricted to 60 cards MAXIMUM per the newly instituted Master Rules.Also, you can have a MAXIMUM of 15 cards in your Extra Deck. There is no "minimum" requirement of the amount of cards in your Extra Deck.For your Side Deck, you must have 15 cards. You can choose not to have a Side Deck; however, if you do, you can have no more, and no less than 15 cards.
A side board is a set of no less and no more than 15 cards that goes with a certain deck. In between duels in a match (3 duels) you are allowed to swap cards from the primary deck with the side deck that it is assigned.
