No it is not
Yes, if you tribute Set them from hand, or flip them face-down using the effect of another card.
You cannot manually Tribute a card without due process. A card can be Tributed via an effect or a Tribute Summon. Therefore, you could not Tribute a monster and send it to the Graveyard without some game mechanic occurring afterwards.
You can, only if something specifically says you can. Tribute for most Ritual Spell Cards can come from hand. But if the card doesn't specify, the tribute must come from your side of the field.
You can never tribute an opponent's monster unless the card specifically says you can (Lava Golem, Soul Exchange).
Only if a card specifically states you can (Ritual Summons, for example). At other times, including Tribute Summons, the monsters must be on the field.

It requires 1 tribute
To tribute a card, you must send it from your own side of the field, to your graveyard. If cards like Macro Cosmos are in play, then the tributed card goes out of play - Macro Cosmos does not prevent you from tributing. You must have a 'reason' to tribute the card, either for the summon of a higher level monster, or the activation of another card, etc. You cannot tribute something for no reason, nor can you tribute a card you do not control unless specifically directed to by something like Soul Exchange. Lastly, tribute is from the field, unless stated otherwise, ie, Ritual Summons.
It all depends on the tokens being used. They can be used to Tribute Summon unless said otherwise on the card. For example, the card "Scapegoat" says: "...The tokens [summoned by this card] cannot be used as a Tribute for a Tribute Summon."Take note of this last condition (a Tribute for a Tribute Summon). That means the tokens can be tributed for a Special Summon for monsters such as "Destiny Hero - Plasma".Tokens that can be used for a Tribute Summon include: "Stray Lambs", "Statue of the Wicked", "Fiend's Sanctuary", and "Dandylion".
