Is the stress/accent always on the last syllable when words end with 'han': sinultihan, basahan, dumaghan, etc. Are there exceptions? Does this apply also to 'hun' suffix?
First, let us define the suffix in question. Actually, this suffix is [-Han]. The H represents the /h/ sound that appears when the base word ends with a consonant.
There are multiple meanings of [-Han]. The general rule is when it's a verb, then the penultimate (second to the last syllable) is stressed; when it's a noun, then the ultimate (last syllable) is stressed. For example:
Basa + -Han = Basahán --- thing to read something on.
Saka + -Han = Sak'an (technically it's saka'án but, due to syncope where usually the phonemes a'án get's shortened to C'an where the C denotes the previous consonant, it becomes sak'an) --- somewhere where one goes up to.
