Can the neccessitive -meli suffix be used with other tenses?

For example:
öğrenmeliyim - I must learn

But are these correct?
öğrenmeliyorum - I must learn now
öğrenmeliyeceğim - I must learn in future
öğrenmeliydim - I must have learnt
öğrenmeliyordum - I must have been learning

I must learn now şimdi öğrenmeliyim

I must learn in future gelecekte ogrenmeliyim

I must have been learning öğreniyor olmalıydım

these are ok
