You have five monster slots on your Field, so even a card that can summon an unspecified amount of monsters (like Return from the Different Dimension) you will still only be able to summon a maximum of 5 to your own side of the field. There are no cards that can increase this, and Trap Monsters take up a monster card slot so it's not like you could have five regular monsters and an Embodiment of Apophis.
No, your opponent cannot Normal or Special Summon any more monsters. They can, however, Tribute Summon monsters if they will end up having fewer or an equal amount of monsters as you. In this scenario, your opponent couldn't Tribute Summon a Level 5 or 6 monster because they would still have one more monster than you. But he/ she can tributed both monsters for a Level 7 or higher monster since they would end up with one monster. The same rule applies to tributes for a Special Summon for cards like "Destiny Hero - Plasma", "Voltanis the Adjudicator", Destiny Hero - Dogma", and more.
If a card looks for a specific number, it will say so, ie, it will specifically say "one" monster. In this case, the opponent has 'a monster', if he has one, two, or even five monsters on the field. So just as long as they've got one or more, and you have none, then you can special summon Cyber Dragon.
Generally, you can only Normal Summon once per turn. However, there are some cards, such as Ultimate Offering and Double Summon that allow you to Normal Summon multiple times.Special Summoning has no limit besides the 5-card Monster Card Zone input. You can Special Summon as many cards as possible in a single turn unless another card specifically prohibits such actions such as Summon Limit.Ultimate OfferingTRAP/Continuous TrapAt the cost of 500 Life Points per monster, a player is allowed an extra Normal Summon or Set.Double SummonSPELL/Normal SpellYou can Normal Summon 1 additional time this turn. You can only gain this effect once per turn.Summon LimitTRAP/Continuous TrapNeither player can Summon more than two times per turn.
The stars are the monster's Level. If you want to Normal Summon a monster of Lv5 or 6, then you must Tribute Summon it by tributing a monster from your side of the field. If the monster is Lv7 or more, you must tribute two monsters. Levels have little effect in-game, they only have an effect when another effect specifically looks at them. So Burden of the Mighty looks at a monster's level to determine how much ATK loss it suffers. The most important thing Level does is how it works with Synchro Summoning. To Synchro Summon a monster, generally you must send a Tuner, and one or more non-Tuners (some rare cases allow more than one Tuner, others require specific components) with combined level equal to the level of the Synchro Monster. So Lv8 Stardust Dragon could be summoned using Lv2 Krebons + Lv6 Destiny Hero Malicious.
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.
Yes, you can use the trap card Ultimate Offering which you would have to pay 500 lifepoints for each extra normal summon, or there is a spell card called Double Summon which allows 2 normal summons.
Only if it has an effect that lets it attack more than once per turn, like Asura Priest does.

no, the tuners level and the non-tuner/s level must equal the level of the monster you wish to Synchro Summon.
yes but the damage from the first attack doesnt add on to the second attack
yes. monsters like giant rat or shining angel lets you summon a monster when they are destroyed by battle, so if you are battling and you attack and kill your own shining angel, you can summon another monster and attack with that one.

Yes, they 'control a monster' if they have one or more. The wording for an effect that can only be used if the opponent has one monster is "controls exactly one monster".
Obelisk is perhaps a little harder to summon, but is a much more powerful monster than Turbo Warrior.
Yes you can normal summon turbo booster, but only when you haven't normal summoned in the same turn already. Rather than being a 'special summon-only' monster, Turbo Booster's special summon is a case of 'you can' do it, if you wish. Like Cyber Dragon, it is a monster who can be Normal Summoned, but has an alternate, special summon method too.
That doesn't really make sense. A special summon 'happens' and then it is finished. It's not something that 'holds' the monster on the field, or can 'wear off' and return it to hand, deck or graveyard. If the effect doesn't say something happens to the monster after the summon, then it is to all intents permanent until something else tries to move it.
