Is a monohybrid always heterozygous?

Yes, by definition, a monohybrid individual is heterozygous for the single gene locus in question.

What is the difference between a monohybrid and a dihybrid?

A monohybrid cross studies one trait (one gene locus), while a dihybrid cross studies the inheritance of two traits (two gene loci) simultaneously.

Can 'monohybrid' be used as a noun and an adjective?

Yes. As a noun: 'The F1 generation are all monohybrids.' As an adjective: 'We set up a monohybrid cross.'

Is this a common word in English?

No, it is a highly specialised term confined to the field of genetics and biology education.
