can someone explain me when i need use different times in greek language (verb @can@)

When i need to use -Imperfect( μπορούσα) ---Aorist(μπόρεσα) --Perfect (έχω μπορέσει) ---Pluperfect( είχα μπορέσει) --Future Continuous(θα μπορώ) Simple Future(θα μπορέσω) Future Perfect( θα έχω μπορέσει)??
please help me understand it.

μπορουσα- I could (this is continuous, it means an act that was perpetual in the past)
μπορεσα- I could/ I was able (momenteral, meaning the act only happened once or for a limited time)
εχω μπορεσει- I have been able
ειχα μπορεσει- I I had been able
θα μπορω- I will be able (I will always be able or for a long time)
θα μπορεσω- I will be able ( for once or for a short amount of time)

Hope I helped at least a bit

θα εχω μπορεσει

sure u helped as well) thanks so much for explain.
