need some help with my gauge lights

In the DIY section, theres a post that talks about swapping out your gauge bulbs with red ones, to kinda get cool red look to your gauges. The guy who wrote it had a Teg, and the bulb size for those are 194R.

Well on my civic, theres one of these 194Rs in the middle, but theres also 4 other smaller ones, which i cant find the size of...and i cant find replacements anywhere

any idea what size these other 4 smaller bulbs are and where i can find them in red?
