I paid off our entire co-signed loan by myself — can I now collect reimbursement from my co-debtors for their shares?

The right you acquired by paying, and its ceiling

Article 1217 of the Civil Code is emphatic about the limit: He who made the payment may claim from his co-debtors only the share which corresponds to each, with the interest for the payment already made. Paying the creditor in full does not make you the creditor in full. You step into a claim against each co-debtor for that person's own portion and nothing more, so with two others on a debt divided equally you are recovering two thirds, in two separate shares, and you carry the last third yourself. The word only is there because paying debtors routinely assume the opposite.

The payment has to have extinguished the obligation

The article opens by stating that payment made by one of the solidary debtors extinguishes the obligation. That is the event which converts you from a debtor into a claimant, so the first thing your co-debtors will attack is whether it happened. Keep the official receipt, the bank's statement showing a zero balance, and any release or cancellation of the note. A restructuring, a partial settlement or a payment made by someone else on your behalf will complicate the claim, and if the creditor is still pursuing the account the obligation plainly has not been extinguished at all.

When a co-debtor cannot pay you back

The risk of an insolvent co-signer does not fall on you alone. Article 1217 provides that when one of the solidary debtors cannot, because of his insolvency, reimburse his share to the debtor paying the obligation, such share shall be borne by all his co-debtors, in proportion to the debt of each. So on a three-way debt where one is genuinely insolvent, his portion is divided between you and the remaining solvent debtor rather than left entirely with you. Note that this operates on actual inability to pay, not on unwillingness — a co-debtor who simply refuses is someone you sue.

Interest, early payment, and what fixes each share

Interest runs on the reimbursement from the payment you made, which is why the exact date matters and why an undated receipt is worth arguing about. Article 1217 adds one qualification: if the payment is made before the debt is due, no interest for the intervening period may be demanded, so settling the account early costs you the interest for the time you gained. What fixes each co-debtor's share is the loan document or whatever arrangement the three of you made about who received the proceeds. Where nothing was written down, that allocation is the part of the case actually in dispute.
