Just use a ritual spell and read its effect. You also need the ritual monster that it says on the card.

No, because it wasn't 'properly' special summoned. To be able to special summon a Ritual Monster from the graveyard, it has to be initially summoned by Ritual Summon. Ritual Foregone does not Ritual Summon.
only if the monster has been summoned to the field, and the summon was not negated. also, if the card says 'this can only be -insert summon type- summoned by -insert ritual/Special summon info- ritual summon only (this card can only be ritual summoned by) -Only ritual summon Special summon only(This card can only be Special summoned by) -Only special summon, hope this helps.
Obelisk the Tormentor (Effect Monster) is not Ritual Summoned nor does it require a ritual. To summon Obelisk the Tormentor, you must Tribute 3 monsters (it is treated as a Tribute Summon).
A tribute summon is a form of Normal Summon. So that means you can only tribute summon OR normal summon ONCE per turn.
Only if the card specifically says it can summon a Ritual Monster, like Ritual Foregone. Otherwise, you can't do it, cards like A Hero Emerges, or Monster Gate, cannot special summon a Ritual Monster.Also if you summon the Ritual Monster properly, by Ritual Summon, and it is then sent to the graveyard for whatever reason, then you may bring it back to the field using cards like Monster Reborn. However you cannot simply discard a Ritual Monster from hand and try using Monster Reborn straight away, they are a form of special summon only monster, simply by being Ritual Monsters.
