Is it okay to take prednisone for asthma flare up, with nortriptyline (pamelor)?

Yes. they have very little interaction with each other.
Should be fine. The only medications that are absolute no-no's for use with nortrptylline are meds that inhibit serotonin uptake, such as MAO inhibitor meds. Prednisone does not fall into this class of meds so should be just fine to take along with it. If in doubt further, request the pharmacist do a med intedaction check when you pick up the prednisone - they have computer software that can show problems.
