Can these be used on 125V applications as well?

Yes it’s the amount of amps not volts that blow a fuse

Is the 250v voltage rating ac (vac) or dc (vdc)?

It makes no difference if it's AC or DC. A fuse is an inert component and works the same on AC and DC.

My machine needs fuse t8a h 250vac. does this product fit my machine?

I do not think so. "t8a h 250vac" may mean slow blow "t", 8 amp blowing current "8a", high current "h", 250 volts AC circuit "250vac". MCIGICM has fast (quick blow), which is necessary for electronics using transistors. For myself I always want or need: what does the fuse look like, fuse dimensions, markings such as you are using. Markings may have extra spaces or not. Slow blow are probably not transparent or are ceramic rather than glass or ar glass with a lot of stuff in them rather than just a wire or strip (with narrowing?). I looked up 'electrical fuse' on wikipedia and went from the text to footnote 7 for an Australian fuse company's page on fuse markings: https://www.swe-check.com.au/pages/learn_fuse_markings.php

Are these standard-sized fuses, ie, dimensions?

As far as standard-size, all I know is the original fuse I removed was the same as what I used in the assorted fuses. Same length and amp.
