you can equip it with up to five equip cards unless you have other spell or trap cards on the field then you could only equip it with as many free spaces there are
There is no limit to how many cards can be equipped to a monster unless it says so on the card. The only limit is how many you can have on the field at one time, so the de facto limit is 10 (5 on your side of the field and 5 on your opponent's side of the field).
Up to 10. After that, there are no more slots in either player's zone for Equip cards to be placed.
yes you can equip spell card cards to an opponent's monster unless the card states so a good example of this is snatch steal
Yes, and in fact several Equip Spell cards would be useless if they could not, such as 'Snatch Steal' and 'Mark of the Rose'.
Yes. Cards like 'Snatch Steal' would be useless otherwise.
Monsters who go into the S/T zone for any reason are then treated as Continuous Spell Cards or Equip Spell Cards depending on what it is doing. It is no longer a monster card so is unaffected by anything that specifically affects monster cards, and cannot be tributed for a tribute summon, etc. However if something required you to send an Equip Spell Card to the graveyard, you could use that monster.
Up to 10. After that, there are no more slots in either player's zone for Equip cards to be placed.
If an Equip Spell Card is sent back to the Deck, it is no longer equipped to a monster, and therefore, the monster does not gain the benefits. If a monster equipped with an Equip Spell Card is sent back to the Deck, the Equip Spell Card is destroyed.

No, even if your Equip cards Equip to your opponent's monster, or if your monster who has an Equip card has control switched to the opponent, the Equip card itself remains on your side of the field.
Yes. Monsters that are acting as Equip cards, are considered to be Equip Spell Cards and are affected by everything that normally affects Spell Cards. So spell destruction cards will affect them while monster destruction will not.
Equip cards can never be attached to Set monsters. They can only ever attach to a face-up monster.

Yes, monsters acting as Equip cards are treated as Equip Spell Cards and are treated as such for the purposes of Spell destruction card.

10 equip cards can be equipped to 1 monster :)
You have to summon them first - they equip by using their Ignition Effects, which can only be done when they are on the field in the monster zone.
You cannot voluntarily move an Equip card from one monster to another, or unequip it and have it be destroyed, unless another effect lets you do so. Tailor of the Fickle is one card. The other situation is with Union monsters who turn into Equip cards. These can unequip themselves as an activated effect and summon themselves back to the monster zone.
