Exchanging one currency for another is permissible, and the rule governing it is simple: when the currencies are different, the amounts may differ - that is just the exchange rate - but the exchange must be immediate. Both sides must be settled at the same sitting rather than one side being deferred. A normal transaction at a bank, an exchange counter, or through a remittance service settles immediately and satisfies this comfortably. So does sending money to family abroad, which is an ordinary transfer plus a fee for the service. What fails the requirement is deferral: forward contracts fixing a rate today for settlement in three months, currency futures, and speculative margin forex where positions are rolled overnight with interest. The distinction is between exchanging currency because you need the other currency, and taking a position on where a rate will move using money you borrowed.

Between different currencies, yes - the amounts may differ freely, and the exchange rate is precisely that difference. The requirement is timing rather than rate: both sides must settle at the same sitting. Where the same currency is exchanged for itself the amounts must be equal, which is why swapping a thousand rupees for eleven hundred is riba however it is framed.
Yes, straightforwardly. The exchange happens at a defined rate, the transfer is initiated immediately, and the fee is payment for a service. Compare the total cost across providers rather than the headline fee, since many take their margin in the exchange rate instead of the stated charge - that is a fairness point rather than a permissibility one, but you are entitled to know what you are paying.
Because three things stack up. You borrow to control a position many times your capital, which is interest-based leverage. Positions held overnight incur or earn swap charges, which are interest. And nothing is genuinely exchanged - most positions close without any currency changing hands. Currency exchange is permissible; a leveraged bet on a rate with no possession is a different transaction entirely.
Spot conversion with disclosed cost
Banks, exchange counters and transfer services settle immediately, which satisfies the requirement. Comparing total cost across providers - fee plus rate margin - is worth doing because the difference on a large remittance is substantial.
Ask for the total cost including the rate margin, not just the stated transfer fee.
