My rough translations of the photo captions, clockwise from top left are:

• -
• Sport
• Profesional
• Profesional

I think that fuller labels might be:

• Triplex (front derailleur)
• Triplex Sport (front derailleur)
• Triplex Profesional (front derailleur)
• Triplex Profesional (with undrilled cage and no cable adjuster)
